Without failure there is no achievement.
The process of achievement comes through repeated failures and the constant struggle to climb to a higher level.
Reaching the top is a monumental achievement, but remaining there may be the most spectacular feat of all.
Small disciplines repeated with consistency every day lead to great achievements gained slowly over time.
The truth is that teamwork is at the heart of great achievement.
No one achieves greatness by becoming a generalist. You don't hone a skill by diluting your attention to its development. The only way to get to the next level is focus.
