How to Really Become Pro Hacker ?

My question over here is that how could one newbie or even intermediate techie start its path to become pro hacker like even bounty hunter , finding new vulns , exploiting/writing own scripts .Like even though one learn java/any programming languages like java,python,C,C++,etc from sites like codecamp, codecademy they dont teach you stuff about hacking/exploiting . I think my question is clear enough now !
