7 Things You Can Do to Become a Better Developer (huffingtonpost.com)

Port a program / library from one language to another. It's great fun. Make sure you know one language well, and the other not so well.

I'm having fun at the moment porting Flash and Javascript games to Objective C (sometimes using the Cocos2D framework, sometimes not)

Porting is great because sometimes it's mindless grunt work (just map functionX to function Y) and sometimes there's more important considerations. If I'm feeling lazy or tired I'll stub out the hardest stuff and come back to it later when I'm more alert.

Good fun!

this should read "7 things you can do to become a better person" from my point of view it doesn't really apply to development.

Surprised to see that gaming is not on there. Studies have found that gamers have an enlarged cingulate gyrus in the brain. This structure has been linked with impulse suppression, so this should help us resist the impulse to do things the wrong way!
