Answer: The folks with a goal and a really big why.
What is your musical goal? Maybe it is time to revisit your reasons for lessons. Brian Tracy encourages people to rewrite their goals everyday. No kidding. It works, I've been using this tactic successfully for years in business and my hobby drumming.
Second part is your "why". This is the fuel of life and focuses our efforts. It is imperative we don't waste our greatest and most precious resource, our time.
The bigger the goal the bigger your why needs to be. Give this some thought. I practice because I want to continue to jam with professionals as a drummer. I practice with the long-term goal of raising my drumming skills to the level of my piano skills.
