How do i become a grandmaster in chess

Play Fide tournament, get high enough elo, then play tournament for the norms, if you get all 3 norms and 2400 elo, you can become a GM

Are there tournaments for beginners? :blush

Yep, just get really, really, really good.

P.S. - Is it 2400 elo? I thought it was 2500. Not sure, though.

Being born to fairly comfortable middle class parents who can send you to a good school, pay for coaching, and foot the bill for hotel stays helps.

Here is the fullexplanation

Being born to middle class parents who emphasis school, university and academic education probably doesn't help. Many world-class performers, be it tennis, football, skiing, diving, chess, etc. Got there by putting 110% into their passion. The middle classes (including myself) often end-up average performers, as it's never more than a serious hobby.

1) Start at a very young age.
2) Show a strong natural aptitude for the game.
3) Develop a passion for the game which has you studying and playing for many hours per day.
4) Have parents who encourage you and can afford to get you top-notch coaching and are willing to sacrifice time and money to travel to strong tournaments with you.
5) While playing in strong tournaments, get 3 GM norms and a rating of 2500, and you too will be a GM.
6) Sadly, if you are on here asking the question in the first place, it will never never ever happen. Simply enjoy chess.com and cultivate other hobbies and career opportunities.

U git gud.

Hello!

Become a grandmaster with this one weird tip!

you don't unless you want to 

There's a really simple secret to getting GM I really want to share. All you have to do is-

And neither should it be. 

Study, play , analyse by playing online until you get 2200-2300 in blitz or rapid here.

Otherwise,  you will simply get smashed OTB, you are far away from any titles.

If you're referring to the literal process, that has been answered. If you're referring to improving your level of play to that of a grandmaster - I think most people, with enough meaningful study and practice, can improve to around the level of Candidate Master. Whether you can improve beyond that is far from guaranteed. 

Honestly, you should check out your national tournaments. I believe for you it's Federación Española de Ajedrez if your flag is correct.

FIDE rated tournaments are expensive, and so only people who are "good" are going to find it worth it to pay.  

Its a hard challenge, However it pays off to play with the big leagues. All you need to do is study, play in USCF tournaments. i am sure there is one not too far from you, Since there are plenty from where i am at. Of course you must get a rating of 2500, 2700 and your dreams will come true.
