If you need to ask How to Become a Hacker, you are not going to be one. It all depends on your personal curiosity, either you have it or you don't. PS: Found 0day on Paypal when I was 12 in the early '00s, never got paid or recognized for it :(
There is a certain kind of person that will become some kind of hacker no matter what, but with advice and guidance they will get a lot further than without.
So, even though it sounds obvious : the number one priority is meeting other people, sharing information. Social skills are sooo important if you're not an absolute genius...
