Avoidance and ego

I learned a very important lesson from this: most of our suffering comes from avoidance. Most of the suffering from a cold shower is the tip-toeing your way in. Once you’re in, you’re in. It’s not suffering. It’s just cold. Your body saying it’s cold is different than your mind saying it’s cold. Acknowledge your body saying it’s cold. Look at it. Deal with it. Accept it, but don’t mentally suffer over it. Taking a cold shower for two minutes isn’t going to kill you.
Coindentally, that's what I am trying to do. 
The fear ahead is always more suffering than the actual pain. 
It’s the awareness my brain was running off in the future and planning some fantasy scenario out of ego. I was like, “Well, do I really care if I embarrass myself? Who cares? I’m going to die anyway. This is all going to go to zero, and I won’t remember anything, so this is pointless.”
Then, I shut down, and I went back to brushing my teeth. I was noticing how good the toothbrush was and how good it felt. Then the next moment, I’m off to thinking something else. I have to look at my brain again and say, “Do I really need to solve this problem right now?”
It's hard to be aware in every circumstance. But it worths trying to minimize ego.
