This is what I do to celebrate or otherwise mark small occassions: get a new Star Wars figure for the collection. I know, pretty silly and juvenile. What can I say: I'm a school board candidate who still has a lot of kid left in him. But I don't see anything wrong with that.
Don't take life so completely seriously every second of your life. You can't put it into real perspective unless you take time to let your inner child come out and play some.
