Now what do I do?

Hello... I'm new to cracking in general. I've been doing the simple "fishing" of serials. It's fairly easy although I sometimes feel like I'm just stabbing in the dark. What are some good tutorials that I can learn more from? I'm a decent programmer (c++/c#), but not an ASM programmer. Any other hints? I've been trying to crack some programs that have compression or encryption, I'm kinda a newbie at that. Same thing for keygens... I'd like to create some but I'm not sure where to start.

Thanks for any advice.
