As a CTO you'll work a lot with people, the best resource you can get is related to people. Get a mentor, read books about dealing with people in the most optimal way for you and the business (closing deals, negotiation, psychology etc). Also learn how to develop people. There are a few books on this, but nothing beats experience and being reflective about it. Every situation is specific and it's up to you to strategize how to develop people in your team, finding out what are the right buttons to push.
