You simply can't and you won't. I'm 26 and started at 21. Even though I'm reaching 2000 tactics my play level in this website is still around 1500 rapid and 1450 blitz. One thing I've noticed is that no matter how much you study, practice and do tactics, it simply takes time for things to 'get in'. Time is also part of the studying.
How easy is it to become a GM?

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
It is very hard to become a GM. You have to get 2 or more GM norms and have a performance rating of 2600

you must start playing when you're a child and never stop, and maybe you could be a gm, maybe...
There's a few who started after 11 and made GM, but it's rare.

I only know one chess player who started at 24 and became GM, that is Chigorin.Even if you start late you must have talent, any player stuck at 1200 will never become a master. Many experts have a hard time becoming a master and never reach master. How can a 1200 online player even think of GM title when he can't get online rating 1800, its so impractical.
Its better to set reachable goals and after obtaining it; set another reachable goal; reachable goal and it should be set at least 200 points above your current rating.

Times are different now. Chigorin was born in a different time. You can't compare that to the level of competition you have today. If you aren't a GM by age 3 you can forget it.

Conversations about religion are more unreasonable than my original question.
you are insane thinking about becoming a gm. you need more than 50000 hours of practice (not joking)

Why aim to be a GM? Shouldn't your aim be just to become good at and enjoy chess? Morphy never became a GM; It didn't seem to hurt his career.

An FM said that it takes around 20000 hours to become a titled player (CM)
really? must be a joke

If you're serious about wanting to reach GM, you should hire a professional coach (ideally someone who is already a GM). Doing it any other way will just be slower, and more likely to fail.

If that’s your dream then go for it and don’t let anyone tell you different .
you asked someone earlier in the thread why they stopped progressing . Let me give you an analogy that maybe makes more sense , maybe comparison is a better word .
becoming a Gm is kind of like being a math prodigy , and some people no matter how hard they study or how long they spend working on it will eventually hit a level of math they can not get passed, where as others look at it and it just makes sense .
some people work very hard from a young age and train there entire life to become Gms and even then it doesn’t happen for them .
"To become a grandmaster is very difficult and can take quite a long time! ... you need to ... solve many exercises, analyse your games, study classic games, modern games, have an opening repertoire and so on. Basically, it is hard work ... It takes a lot more than just reading books to become a grandmaster I am afraid." - GM Artur Yusupov (2013)
