How can someone become the greatest chess player like Magnus Carlsen? How can someone become the greatest chess player like Magnus Carlsen?

I have been playing chess since I was 12 years old, but still I am an average chess player. 

Does it take genetics to become a Super GM like Magnus Carlsen, Garry Kasparov, or Vishy Anand? Or have they all followed some path towards their greatness?

What steps could I take or attributes should I possess in order to become the number 1 rated player in the world?
Talent: Generally the role of talent in chess is vastly overrated, but for those at the very top anecdotes of impressive memory feats are quite common. (Like Carlsen learning hundred of statistics about norwegian municipalities as a four year old, or Fischer repeating a phone call in islandic verbatim, although he didn't understand a word, etc.)
Early exposure: The vast majority of the top hundred GMs nowadays learned to play chess before they turned ten. Often even before they turned six. Early exposure is important for chess moves and concepts to become completely ingrained in your brain, just like the grammar and vocabulary of your mothertongue is. 
Hard work: Even those players that are allegedly lazy spend an incredible amount of time on chess. Becoming a strong chess players requires a huge amount of knowledge and abilities. The earlier you start, the harder you work and the more directed this work is, the younger you will still be when you have acquired the knowledge necessary to be a Super-GM. 
Drive: If you have the abilities and the knowledge to play on a 2800 Elo level, it still doesn't mean that you actually play on that level. Additionally you need the energy and will to win, that allows you to put every ounce of your ability into every game you play. Some people claim that motivation is the main reason the playing level generally drops after you hit 40. 


So the steps to become a Super-GM are actually quite simple: Start at age 4, train chess every day for 6-8 hours under the direction of an experienced trainer, compete regularly against slightly stronger opposition and be born with an exceptional memory and a killer instinct.
