Is it Me?

I have thought a lot lately about Alison's comment on my previous post about changing jobs. How it doesn't really matter where I work, or how many different jobs I work as, as long as I am working and providing for my family. I agree. Especially at this time in my life while I am STILL going to school. I know that one day I will have that job I love to go to work to and will work at for 30 years or whatever and retire from and all these "temporary" jobs will just be a vague memory of the past.
But I sitll can't help but wonder if it is me. You know I have been laid off of a lot of my jobs indicating that the job was lost through no fault of my own. Others I have left volentarily to get a better schedule or better pay or just try to get better management. But I have honestly never heard of anyone having this many jobs, especially in such a short time frame. So I wonder, is there something I am doing wrong, or is it just the way it is. I think other people also think it must be me. Even if they don't realize it, somewere in the back of there minds they are thinking, what is this guy doing? Why can't he just stay at one place? or is he really getting laid off, or is he getting fired and just passing it off as a lay off to feel better about himself. Most of this I figure other people are thinking because I wonder the same things, all but the getting fired part because I know it was a lay off.
No matter how you look at it I wonder, why? I have always been a person that has felt that everything happens for a reason even if we don't recognize the reason at the time. Good or bad it is all for a reason. I think that most of it is so we can learn something, grow, become stronger better people from our experiences and trials. But sometimes I realize that things just happen because of the choices we make (usually dumb choices). You know the whole cause and effect thing. But even then I guess they happen so we can learn to make better choices. So is my long series of jobs just a trial, a bump in my lifes road that is there to help me learn or grow? or is it the result of stupid choices I make?
