Part of the Zen of Pedro is my basic philosophy that I am 100% responsible for my life.
I have been dealt a bad break or two over the years, and those things happen, I didn't bring it on myself, and it wasn't through bad luck or fate that it did. These things I cannot control, but what I can control is how I react to them. I haven't always made the best decisions, in fact it seems sometimes I sit and wonder how I could have been so dumb five, ten years ago. I am sure five years from now I'll probably think I am doing something stupid today.
I know a lot of people that think life is beyond their control, and if you think of it in an instant gratification sort of way, yes, you cannot become a doctor tomorrow, but tomorrow you can find out what it would take to start. It may be that you lack all the resources to do it, but it comes down to things you can control.
Maybe you can't have all your hopes and dreams, but it shouldn't stop you from trying to get close, and maybe end up with something that will at least make you happy.
This moment of introspection was brought to you by the letters I, and AM. Ok, actually, it came off a recent TV show, when one of the characters had said "Embrace the Suck" which I thought was a beautiful way of describing life. You really have to make the suck your own, because once you accept responsibility, then you can go about changing it.
Oh a caveat of this is; this is what works for me. If you don't think it will work for you, or if you tried it and it didn't, I can't help that. That would be me taking responsibility for your life, and I can't do that
Edit: To give the cliff notes version, this says "Excrement Occurs" (keeping it SFW) You can't stop it, there's no reason why, and you have no control over it. The only thing you can control is how you deal with it, and accept what you have to work with.
