Fate vs. Predestination

I was wondering about that arguement lastnight as I tried to sleep.....I really don't know where I stand when it comes to it. I believe to a certain degree that everything happens for a reason, but not that it is controlled and already mapped out by a higher power. I also think that whatever os to happen to us can be changed by something we do........???? I guess for those who believe in whatever it is they choose to believe in......go ahead and believe it. And for the rest of us who just want to be......let us be.......
