How easy is it to become a GM?

They just do not associate with us. They have a GM fora.

5 hrs a week
or 20?
I think the 5hrs a week won't get him far at all. unless those 5 hours are just studying and don't include playing time.
I am 25 and just started playing chess. How hard was it for you guys to become Grandmasters?
I'm hoping that in a few years time I can be grandmaster if I put in about 5 hours a day of preparation. That's almost 10,000 hours. 9125 to be exact (5*365*5). From what I know, becoming a grandmaster used to be hard, but now it's easy because of computers. That's why there is so many grandmasters nowadays. So if you guys could tell me how you became grandmasters I would appreciate it. Please discuss study time, preparation, how long it took you, diet, etc.
Thanks guys
the question is more like -- if it is possible with hours of study to beat me ... I doubt it
I think you are a weak player who cannot even draw with me... Yet you talk about being a gm --
LOL .. Pathetic ... The only way you can beat me is with an engine ....Pretty sure you would start doing that soon to become a "GM"

@danny.
do you know about how strong a 90% tournament player.
its also something to appreciate that the population of tournament players is far better at chess than just the casual internet chess player.
as a beginner; you could just as easily vow to be the WCC as to be an expert.
even though the latter is more possible.... its still incredibly difficult to be an expert and requires an amount of dedication and work a beginner couldn't appreciate.
According to the USCF website, in 2004, a USCF rating in the 1800's puts you in the top 10th percentile... USCF tends to run about 100 points inflated compared to FIDE. So in 2004, a FIDE rating in the 1700's puts you in the top 10th percentile. I can't find anything more recent. Maybe someone else knows?

then I got badly beaten by a guy at 90% (last tournament). that's comforting.
anyways 90% is a good long term goal.

but note the question of a tournament. I don't ANYONE should have any goal in OTB chess without first attending a OTB tournament or club meeting and see what they are up against.
who knows? perhaps you will not like playing OTB chess.
: you don't know until you try

If you work on devising a chess engine brain chip, it'll be still probably easier to get than a GM title starting at 25. Your questions and comments show a remarkable lack of understanding of chess and an underestimation of the whole depth of the game itself.
I have replied to your post because I have a situation almost similar to yours. I started playing chess at 21yo (2 years ago) and now I'm somewhat around 1600 elo, and have defeated a few 1700s at my club. I regularly study 2 hours a day and I can say I'm still making gradual progress. If I had the time to study say 8 hours a day maybe I could dream of reaching expert levels in a few years, and that's still miles away from lowest GM levels! What I'm saying is that if you have the personality and talent for the game don't hesitate about putting as much effort as you can into it. You'll love it and it will reward you in many ways. You don't need to be a GM to appreciate and enjoy chess. You don't need to be Kobe Bryant to play and enjoy basketball. But don't set your standards too high as it only brings about disappointment in yourself.

The numbers OP is talking about might get him to expert if he has the talent.
Expert is not that hard to achieve if you put the effort in. It's beyond that where it gets exponentially more difficult to achieve each level.
I started at 1177 in a tournament in 1996. Started playing regularly in March 1997, and 4 1/2 years later, in August 2001, I reached expert.
Now, in 2016, still trying to reach that elucid title of Master. Unlike the pipe dream that the OP figures he'll achieve, I figure to reach Master one day, and possibly even FIDE master. I will never be an IM or a GM, and acknowledge the fact unlike the OP.

you say its not that hard thriller
but many people haven't/couldn't. perhaps they didn't the effort in. idk. but I still think chess improvement is a very personal thing. perhaps some didn't have the dedication or the vision or perhaps they did.

Define? Is it hard to reach Expert? NO! The only thing hard about reaching expert is having the motivation to do so. With proper study habits, meaning getting out a chess board and book and seriously studying, not passive studying that does you little to nothing like watch chess videos, you tube videos, or clicking with a mouse to go thru database games, and playing in tournaments regularly, meaning minimum of 50 over the board, slow time control games per year, and you should have no problems reaching expert in 5 years or less - age plays a large factor in that. It took me 4 1/2 years starting at almost 22. I've seen kids reach expert in 2 to 3 years.
Beyond that, it's tough as sh*t! Advancement is NOT linear. It's exponential! The increase in strength to get from 1900 to 2000 is not the same as getting from 2000 to 2100. You can't say that if you gain 100 points in 4 years that you will gain another 100 in 4 more years. Doesn't work that way!
I'm going to go out on a limb and say that the OP never comes remotely close to touching 2400, let alone GM!
And when I say that, I mean a legit 2400! Over the board! Standard time controls. None of this Internet Bullet or Internet Blitz horsesh*t. You reach 2400 internet bullet? Congrats, you've proven NOTHING!

There are 492 Billionaires in the USA. There are about 100 chess grandmasters-become a billionaire it is easier.

They have a GM fora.
fora > forum (if you intend to express the singular )
English is my 2nd language. Thank you for correct.

OR
- just plain, enjoy chess
- put in a moderate amount of time and effort at it
- Play in a club and attend tournaments as your able to (expense and difficulty)
- keep doing this for months to years
and see how far you can get.
25 might be too old to hope for Gm, but its a better time in life to improve, than for example, 42.

Assuming you will have the talent.
Here is what you will need.
Study chess at least 8 hours a day.
Travel around Europe and participating in at least 6 strong open tournaments every year.Hire a good coach that will guide you
Hire a good coach that will guide you
That means , no life and someone that will fund all this and will cover all your needs in books , laptops , tickets , hotel rooms , food , coach expenses etc.
If you do all these and assuming you are a great talent , your odds are still somewhere between 2% and 3% to make it.
Assuming you can and you are willing to do all these you have to be able to overcome disappointment after disappointment (and there will be a lot!!!) and get over the fact that you practically sacrifice your life without any guarantee that you will ever succeed in becoming a below average GM(you can't hope for something better).
In some sports you must start when you are kid.
Could you start training now and be an Olympic champion in gymnastics?
Could you even qualify for the Olympic team?
No and no , not a chance , not even the slightest.
Why?
Because your body is not the same at the age of 5 and at the age of 25.
So is your mind.
You think you will read , understand and learn but that is not enough,that is only a very small fragment of the whole process.There is simply an unimaginable quantity of quality information that needs to be absorbed , processed and "wired" in your brain. And while that is relatively easy for a kid it's close to impossible(if not totally impossible) for a grown up.The bad thing is that you have no control over the "wiring process" , there is nothing you can do to make it happen.No training , no diet , no steroids , no drugs.It either happens , or it's not.And your chances that it will happen at that age are close to nil.
Forget GM , dedicate the same time to anything else and you can be a successful "anything you want" without losing your life.
Sure you can be an Olympian. On a recent Geico commercial, a sumo wrestler competes in figure-skating.
Here's the video! http://creativity-online.com/work/geico-sumo-wrestler-figure-skating/50050
See - anybody can do something if they put in the effort! ROFLMAO!
OP should hire 50 GMs. 10 opening spcialist. 10 middle game. 10 endgame. the other can cover everything else.
