There are a lot of things we should definitely not take advice about from celebrities. For instance, I'm a little hesitant to take marriage advice from someone who's been divorced five times. I have a friend who gets really angry when he hears George Clooney wax political, while it doesn't bother me at all. It's not that I ignore George Clooney-I mean, come on, look at the guy-but I don't pay much mind to the political stuff because he's not a politician; he's an entertainer. It's interesting, sure, but that's not what he does best. What I do listen to, though, are celebrities who try to encourage the rest of us to feel good about ourselves. There are a lot of people who use their celebrity to give suggestions to their fans about how to make the most of life. I know I've missed a few, but here are some of my favorites. Some aren't tips so much as food for thought.
