Most of this sight has to do with learning to think right. Differences I have learned that there are definite differences in how various groups of people think. Coaching Men and Women, Juniors through Master's, and beginners to pro's all at the same time was a fantastic learning experience. I was able to make a comparative analysis between them all at the same time as far as psychology, training, and strategies. Most women learn to use the complex team tactics two to three times faster than most men.
Most men automatically race more aggressively and develop faster physically than most women.
Juniors do what you tell them to do with very few questions and most adults regularly ask why. A coach will spend most of his time teaching women to race aggressively, men to think while blasting away, and answering adults' questions. It is not humanly possible to push yourself harder or farther than you believe you can go. If you believe that the best you can be is a Cat 3, then you are right. You cannot be better than a Cat 3.
