In terms of the dark self-doubt and negative space, there a few things that I’ve found very helpful. Because we all experience that, or most humans do. There are maybe some mutants out there who don’t, but I’ve spent time with a lot of successful people. You
know some very successful people, obviously. And everyone, I think, has moments of self-doubt and negative spirals.

So a few things that help me tremendously. The first is a book with a terrible title and great content, but it’s called How to Stop Worrying and Stop Living by Dale Carnegie, that is not his best-known book, but I think one of his most helpful. 

How to Stop Worrying and Start Living by Dale Carnegie. Also a huge winner. I haven’t listened to it, but I’ve read it several times. It is on my bookshelf about 12 feet to my right. It sits there as a constant reminder. It’s kind of a “break glass in case of emergency” book.

I'm a big fan of a lot of his work, in particular not the How to Win Friends and Influence People, but How to Stop Worrying and Stop Living, which I think is a fantastically well written book on anxiety. There’s a bit of material on the physiology and so on that’s outdated but the vast majority is fantastically well done.
