Recomendations - becoming a C soldier.

[Orestes leal <orestesleal13022@cha.jovenclub.cu>]

Hi folks, 2 weeks ago I began to learn C,
my advances are very good, my question it's that,
The topic sounds funny but it's mostly serious,


QUESTION: Studying C 'every day' 4 hours with good understanding,
writing at least 10 programs to test this knowledge every day, the question
it: How Long Can I become a very 'very' good C  programmer to the point to hack in some
kernel of some system or writing good apps without some trouble?

best regards,
