I have to say that regardless of my rating I am going to train and work hard to limit and remove my mistakes during each game. I believe people who reach 2000+ are those of us who can not and will not stop pushing ourselves. It is a sickness, and you should not envy those of us who have it.
Although I would like to have that GM title. I'll find a way to make chess part of my life. Nature finds a way. I don't know how, I don't know when, but I will achieve it.
Or I'll die.
I will say it depends how young you started, the older a person is; it become more difficult to reach 2000 otb rating.
