If you want to learn more about Don and how influential his work has been, I recommend listening the recent Acquired episode about Don and Sequoia [0].
Great episode. Will listen to it again on a long walk today.
I’ve always sought commentary and quotes from Don Valentine to help me learn more about being an angel investor the same way I have have always Warren Buffett’s commentary and shareholder letters to learn how to be a better long-term investor.
