I don't specifically intend to become a Renaissance Man, but I tend to see "opportunities" everywhere. I heard about Windows and programming, I wanted to start building my own programs. I saw my friends playing video games, I wanted to learn 3D graphics and build one of my own (I learnt OpenGL as a result). I saw someone playing guitar, I wanted to play and compose. Though learning guitar took quite a lot out of me.
I tend to see the basic principle behind things, start out nice but lose interest halfway because practice bores me.
