No One Cares What You Had for Lunch: 100 Ideas for Your Blog.
My favorite pieces of advice:
To choose a spouse, find someone who is flawlessly kind but has an incredibly strong backbone. See also: Marry him only if you will be proud when your child turns out just like him.
Don’t make assumptions, and don’t take things personally.
What you give is what you get. When you predict that negative things will happen, they do. The opposite is also true.
*Update: Three more good ones:
Plan less, do more.
Always have a valid passport.
Stop picking at that.
