One challenge is to critically examine your own successes and failures to find a way to attribute the outcomes to something you can control and can change for the future. This could be as small as how you deal with a single person, or it could be a more in-depth examination of how you provide feedback to athletes and how you work with your own staff.
Much in the same way that a single movement or a single workout does not make or break a training cycle, the same holds true for mental skills. The challenge is that the strength and conditioning coach will likely need to reach out to another professional trained in sport psychology to help establish the plan and construct the appropriate interventions.
