As a teacher of the banjo, guitar and mandolin, I often hear the various reasons why someone is not able to practice.
After earning my BA degree, I first attended law school and then moved on to graduate school. My career soon required me to move eight times to four states. Yet, in all these moves and disruptions, I never took a break from my music. I am not claiming to be a poster child for practicing. However, I find it amusing when a child or an adult tells me they are too busy to practice.
When I teach my guitar class for children, 20 youngsters appear on the first day of class, ready and anxious to play. That number sometimes dwindles to a smaller number as the term goes on. A few of the children soon realize that learning a musical instrument requires dedication and effort. When I ask the children to raise their hands if they practiced every day the first week, not many raise their hands. Yet, when I ask them if they watched TV or play video games daily, many of them salute in unison.
Adults are not much different. In the past, I had adults tell me that unlike me, music is not the way they make a living. Music is not their sole interest. They have a family or they have other obligations. My response to such comments is that if I had ever thought that way when I started playing music, I would not have reached the level in which I play today. I never considered practicing music in a manner which would generate income or as a means of making a living. I never let my job, family and friends, hobbies or other interests, or the various moves I made from state to state, interfere with my determination to practice and learn music. I simply practiced because I enjoyed the music.
I guess my rationale is that if you have the time to take a shower (which I hope you do) then you have the fifteen or twenty minutes a day to play the banjo, guitar or mandolin. If you can watch an hour or more of the latest reality shows on TV, then you can practice your instrument an hour a day. It is all a matter of how you prioritize your time. In my case, music just became a passion and a high priority. It was never intended to be a career.
