DS10 has some similar traits and something that seems to have helped is reading about people who have overcome obstacles. It seems to have given him some perspective.

He read dozens and dozens of those biographies with the people with big heads on the cover, the Who Was? series, over the summer. They’re really easy to read and each one took about an hour. He was trying to reach a goal of 100 hours of reading over the summer so he read a lot of them.

I’ve noticed he has a better attitude about mishaps. I’ve also noticed him referring to them when his little brother is being negative.
