In my time, I have been head coach and assistant coach to pro, semi-pro and national league rugby teams as well as the Irish women's team. I have been a sports psychologist and an advisor on performance and setting performance environments in rugby, golf, motorcycle racing, rally driving and many other professional and Olympic sports. I am now a technical diving instructor as well. Why the mini-CV?

When divers on technical dives become task-fixated, critical cues that warn divers that their broader attention is needed can be missed. Psychologist and technical diver, Matt Jevon, discusses the effects and dangers of flow and task fixation in diving.

There may not be an "I" in team, but there's one in "win", "live", "first" and "dive"!

Learning skills from some instructors might be a waste of time. Skills are the foundation of safe and enjoyable diving and the building blocks of all diving certifications. The comment here is not that learning skills is a waste of time, but that if you learn them from the wrong instructor, you may have to re-learn them completely for the skills to be of any use.
