Today, I turn 40. Living on this planet for forty years teaches you a thing or two.
Here are ten things I've learned along the way.
Get in shape and stay there
You can't teach experience
Some people just want to watch the world burn
Always save your source files
Talk to your kids about everything and anything
Never stop learning - you don't know it all
You don't need religion
If you can walk or bike there, do so
Learn from your mistakes (and the mistakes of others)
Take lots of pictures
