Because life likes to be a jerk sometimes, here's one way to avoid sadness--just try to think of something that's coming up in your life you can look forward to! That way, you'll feel better about going through sucky times now because better times are about to come along!
I'm looking forward to spring break, which for me begins on Saturday and ends the following Sunday (March 30-April 7). I don't have to work nearly as much as I had expected, and it looks like I'll have plenty of time to play my two awesome new games, Luigi's Mansion: Dark Moon and Pokemon Mystery Dungeon: Gates to Infinity.
