I didn't touch my trumpet at all today, and I haven't missed a day of practice in a couple months... I thought it would be OK to skip today because I just concluded a series of two hour shows, every day for the past 5 days. I was just feeling a bit guilty about it because I remembered what my middle school band director always said -- everyday you miss a day of practice, you go backwards in your development. Just wondering if any pro's take a day off? I think I read somewhere that some people take one day off every week?
