Poker Analogy

Every situation in life can be related to poker. For example:

Right now I'm in the game with a fairly large amount in the pot. There are a few other people in. I have a three-ten, off-suit. Nothing. Now the question is, do I keep betting, use more money, and stay in the game? Or would it be better for me to just fold and get out while I haven't put in too much? It's not a fun game, and it's not a very fun table. I'm really not sure why I'm even here. Every ounce of common sense is telling me to fold, but I know that as soon as I do, I'll regret it. I don't know why, I just will. There's no chance of me winning; I'm pretty sure one of my opponents has a couple of aces, but I don't want to fold. It's too painful (here's where the poker analogy slightly breaks down a little bit, I suppose). I guess I have to, though. I need to get on, move on, float on. I toss my cards to the dealer. I fold.
