still sick

I dont get as sick as I used to. I'm in really good shape for a 40yr old. Not big, 140lbs of muscle though with no injuries or limits at this point. I'm kinda trippin on it. I thought I would have found a weak link in my body by now. I'll just keep pushing it bit by bit and see how far I go. I'm excited about my future in the martial arts. I cant fully explain why I want to maintain a battle ready life. It feels right.
I need to be my own best friend through this. These folks I'm training with are professional and very good at what they teach. http://www.ncquest.com/default.html
Even so:
What kind of friend am I to me?
"You're the one who talks to you, all day, every day. What kind of friend are you? Are you actively creating a toxic environment for yourself, contaminating your experience of the world? Or are the messages that you send yourself characterized by a rational and productive optimism?"
I'm thinking Im going try to open a new space in my mind for it all. A space wide open, without limits and full of bright, warm potential shining down on me all the time, moving me forward, onward. It will be great!
