I have control over very little, and I know this. However, I yearn for control. It is somewhat debilitating. So much of the time I feel like saying "fuck it, who cares", because I know that I have very little control over the situation, and I am tired of burning up energy beign pissed off about it. The only control I have is how I choose to feel about something, and even then it is a huge internal battle, and lose the battle against my impulses far too often.
So much suffering comes from thinking you have control, then finding out you don't. More suffering comes from wanting control, but not getting it.
I'll give you an example. I come back to the gym after a break. I take control of the situation and start makign decisions that will produce success. Success starts coming and my ego grows. I make tons and tons of improvement until finally my body can't take it and all sorts of injuries pop up. In this moment I realize how little control I have, and what little control I had is taken away. Now I am pissed off and brutally depressed for a bit.
Then I realize that the only control in this entire universe that I own exist in my thoughts. So I will take a step back, take a break, try to keep a good attitude, and wait to heal. I'll do it all over again.
