A problem is anything you want to be different. Even if you want something to stay the same that may change if you don't do something to keep it the same is also a problem. You're still wanting something to be different than it would otherwise be if you didn't take some action. However, just wanting something to be different doesn't in itself constitute a problem. If you accept your wanting as just wanting and you also accept that you're either unable to or don't intend to take any actions toward possibly satisfying that desire, then you don't have a problem. Problems can be internal problems or external problems or a combination.

Problems are a built-in feature of life. As Werner Erhard said, "Life is a game. In order to have a game, something has to be more important than something else. If what already is, is more important than what isn’t, the game is over. So, life is a game in which what isn’t is more important than what is. Let the good times roll."
