motivations

I've always been interested in what motivates people. I've seen people do things out of thier nature for different reasons. What motivates a man to change his side in a war, is it money, power, greed? Could it be that he has his family on his mind when he makes his desions, or could he only be thinking about himself? What motivates a man to leave his family? I do not know the answer to many questions that i have asked and many people can not answer them, maybe its because no one truly knows why they really do anything anymore. What motivates me to write this blog? This question is designed for only me to truly be able to answer yet i can not find the reason i am writing this, maybe its because i have to or maybe its because i feel there are things that should be said that arent, I do not know why. Do we think about our future when we answer questions or do we think about whats only going on now? i dont know why we acted they way we do eighter, but that is for a different time!
