Slow.
When I was in elementary school, I was much quicker than my peers. But then, as my personality started to develop, I began to slow down and everything became tougher for me. I had no cognizance of what was happening to me, so I just assumed that I was stupid. I believed that for a long time, and subsequently spent many years wallowing depression and self-loathing.
Then, in the middle of a very painful time, I discovered MBTI. I realized that I didn't process information the same way as everyone else. That I'm not structured was not due to my laziness or lack of effort, but rather to my personality. And given that most academia is super structured for maximum efficiency, I predictably underperformed.
I realized that if I just had more time to focus and learn, I could achieve at the same level as most people. But prior to my knowledge of MBTI, my god I must have copied/pasted on a bunch of my papers thanks to a wicked combination of hermetic lifestyle, procrastination, depression, and unrealistic perfectionism. Looking back at college/grad school, I wish I had more time to make connections with people who could have helped me develop my unique learning skills instead of dilly dallying with homework all the time. Had I known how to deal with my weaknesses, I think my self-esteem and confidence would have been much higher. I would have benefited much more from a slower pace.
