As a coach you are just as much a performer as your players. This is something we need to realize and understand on multiple levels.
I challenge you to remove the word "don't" from your coaching language. It probably won't be easy, but if you can do it you will probably see big benefits.
I came across an article from the world of soccer that makes some very good points about several aspects of coaching that apply to any sport.
An important skill in coaching is the ability to stay focused on the thing you're looking to train, and to create the right situation to do so.
Access to more and/or better resources is a definite competitive advantage in that they can give you an edge in one or more of the other success factors.

Your relationship with your players - both individually and collectively - can be a massive influence on your success as a coach.
