For Christopher Diaz, getting into the business of teaching mindset wasn’t the typical way to do things. He wasn’t always a motivational speaker with a show and a book that sold a lot of copies. As a child, he worked as a clinical psychologist in the US Navy, where he worked with sailors and Marines. He saw some of them deal with problems that most people will never have to deal with, and he was genuinely interested in what was going on in their minds that made it possible. He never really got rid of that question, it seems.
This long-term obsession is now shown through the Mindset & Skills platform at mindsetandskills.com. Diaz has been writing for more than ten years about what really makes people grow, whether it’s in business, in relationships, or in their daily efforts to be better than they were last year. The blog talks about business, sales, communication, and the mental habits that set people who actually want to improve apart from those who just say they will. It’s a crowded space with a lot of content that makes the same claims. Because Diaz brings his background into his work, it feels a little more real.
As a psychologist, Diaz worked with Paralympians, top executives, and special operators. These are the kinds of people who have studied their own performance because it’s part of their job. He saw that almost all of them had three things in common: being fully present in the present moment, seeing fear as something to move toward instead of away from, and acting like the person you want to become before you feel ready to do so. The last idea goes against what most people want to do, which is to wait until they are ready. Diaz’s argument, which is based on research he has seen during his career, is that readiness usually comes after action, not before it.
As a 2013 Tillman Scholar, he talked to a room of about 400 people at the 2016 Pat Tillman Leadership Summit and presented this framework. The Pat Tillman Foundation chooses scholars based on their ability to lead and their commitment to service. This is important to keep in mind when judging what Diaz brings to this space. He’s not the type to turn to personal growth after a rough patch. He made a living by studying how people work, and then over time he started looking for ways to teach others what he had learned.

One interesting thing about his work is that he also coaches people in sales. This might seem strange for a clinical psychologist, but it makes sense. A lot of what Diaz writes and says is about the identity side of selling, which is the idea that closers aren’t made with scripts but with a change in how a person sees themselves. His position is based on the same psychological ideas he used in clinical settings, but it points in a different direction. It depends on where you’re coming from if that frame works for you, but it seems to work for entrepreneurs who’ve hit a wall they can’t quite explain.
Reading through the Mindset & Skills content makes me think that Diaz is really trying to give people something useful, not just something that sounds useful. It’s harder to make that distinction than it looks. The next step in that direction is the MAS Academy course, which will start in December 2026 and cover mindset basics, setting goals, communication, sales, and thinking like an entrepreneur. It’s still not clear how it will all work, but the foundation that is being built around it shows that someone has given a lot of thought to the time between being inspired and making a change.
