In his TED talk, Stephen Duneier explains that what defines him are not titles, but an approach to decision making that transformed him from someone who struggled with simple tasks to a guy who is continuously achieving even his most ambitious dreams.

For thirty years, he has applied cognitive science to investing, business and life. The result has been the turnaround of numerous institutional businesses, career best returns for managers who have adopted his methods, the development of a $1.25 billion dollar hedge fund and a rapidly shrinking bucket list.

“Every one of my report cards basically said the same thing: Steven is a very bright young boy, if only he would just settle down and focus.”

“What they didn’t realize was I wanted that even more than they wanted it for me, I just couldn’t. And so, from kindergarten straight through the 2nd year of college, I was a really consistent C, C- student. But then going into my junior year, I’d had enough. I thought I want to make a change. I’m going to make a marginal adjustment, and I’m going to stop being a spectator of my decision-making and start becoming an active participant.”

“And so, that year, instead of pretending, again, that I would suddenly be able to settle down and focus on things for more than five or ten minutes at a time, I decided to assume I wouldn’t. And so, if I wanted to achieve the type of outcome that I desire – doing well in school – I was going to actually have to change my approach. And so I made a marginal adjustment. If I would get an assignment, let’s say, read five chapters in a book, I wouldn’t think of it as five chapters, I wouldn’t even think of it as one chapter. I would break it down into these tasks that I could achieve, that would require me to focus for just five or ten minutes at a time. So, maybe three or four paragraphs. That’s it.”

“I would do that and when I was done with those five or ten minutes, I would get up. I’d go shoot some hoops, do a little drawing, maybe play video games for a few minutes, and then I come back. Not necessarily to the same assignment, not even necessarily to the same subject, but just to another task that required just five to ten minutes of my attention. From that point forward, all the way through to graduation, I was a straight-A student, Dean’s List, President’s Honor Roll, every semester.”

“I then went on to one of the top graduate programs in the world for finance and economics. Same approach, same results. So then, I graduate. I start my career and I’m thinking, this worked really well for me. You know, you take these big concepts, these complex ideas, these big assignments, you break them down too much more manageable tasks, and then along the way, you make a marginal improvement to the process that ups the odds of success in your favor. I’m going to try and do this in my career. So I did. I started out as an exotic derivatives trader for credit Swiss. It then led me to be global head of currency option trading for Bank of America”
