I really like this quote because I find that a lot of very smart people overschedule their lives because of insecurity—feeling that if they're not always working, they're not providing value to the world. When people overschedule their lives, they're often overcommitting to things as well, which means they're actually harming relationships along the way instead of focusing on one thing, or at least far fewer things than their insecure, ADHD mind might want them to do. This is very much advice to myself but also advice to people I work with.
