When I was growing up I was was frequently subjugated to violence on a daily basis, over time I learned to zone out of reality, and remind myself that the bruising and cuts would heal and after some time (probably before I reached kindergarten) it just became instant, and I didn’t feel the pain the same way anymore, like I can feel pain, but isn’t something I remember and isn’t in my conscious awareness, like it’s happening outside my immediate focus in a way. Getting over the emotional trauma, on the other hand was a much more difficult thing and took over 15+ years to get over that, but thats a whole different topic.<p>But, even then, I am sometimes frustrated with how difficult it is for me to do creative work when dealing with certain types of pain like headaches, toothaches, fatigue. I could always do basic physical labor while in pain, even headache/toothache/fatigue, but trying to learn anything complicated or do intellectual work was harder. I was decent at endurance running, I think this was somehow related, I would basically zone out how my legs and lungs are burning, and how tired I felt.<p>However, unless I was extremely motivated such that then I could sort of hold onto the task in my mind and zone everything else out, it was next to impossible for me to do focus on it. For example stuff that is mundane, boring, tedious or something I don’t care about, it was very hard for me to get anything done while being in pain, for example I recently got 2nd degree burns all over my face and tore my rotor cuff again (not simultaneously), I was able zone out the pain, but it was hard for me to concentrate on work, or school, until the pressure of getting the work done became so high that I felt it was important to do it, and then I could push thru and get it done, but otherwise I wasn’t able to. I guess it’s like I was in some sort of survival mode, and if certain work didn’t feel needed for survival I wouldn’t be able to concentrate on it.<p>I always wonder how people with chronic pain can even get anything intellectually done, based on reading this, it wasn’t clear to me, but I guess it seems like he is holding a strong motivation to face the pain and succeed despite the pain, which does make sense.
