An expert on human blind spots gives advice on how to think

A lot of the issues or problems we get into, we get into because we’re doing it all by ourselves. We’re relying on ourselves. We’re making decisions as our own island, if you will. And if we consult, chat, schmooze with other people, often we learn things or get different perspectives that can be quite helpful.

An active social life, active social bonds, in many different ways tends to be something that’s healthy for people. Social bonds can also be informationally healthy as well. So that’s more on a top, more abstract level, if you will. That is, don’t try to do it yourself. Doing it yourself is when you get into trouble.
