@elVato: you're mentioning more some of the most well-known (and kinda useful too). I dig deep into real hacking, about being creative and creating your own. A good start would be studying about:
1) Learn how to use many variation of mnemonics;
2) learn how the brain works;
3) understand that even physical exercises can helop you a lot (to learn everything faster and without much suffering so...they're a kind of hack too);
4) Having some free time to let your brain work on the info you studied "on the backstage".
You, are different of me which, in turn, makes us both different of everyone else. The real fun is challening yourself to find the most uncommone hacks which works better for you....and go for it.
if you wanna pick some basics of several languages...why not studying them alone, and focusing on what they have in common?
