Lately I have had very little time at home and when I get home I am very tired. Last night I got home had dinner and had only about 30 minutes to practice bass before I needed to be in bed. I turned on the metronome, played my warm up exercises and some scales / scale exercises. I sounded terrible start to finish. I was really struggling and thought it meant I needed all the more work so I kept going with the scales about another 15 minutes. I still just couldnt get it going on and it was past my bedtime so I set the bass down disgusted and went to bed. The question is: Is this type of forced practice doing me any good? I dont know what else to do because most days will be like this for a while, and long breaks from practicing certainly havent served me well when life has gotten like this in the past, so I want to practice everyday. The obvious answer is to practice a whole lot on the weekends, but last weekend that wasnt possible and this weekend doesnt look much better. I realize nobody can fix my busy schedule or put more hours in the day for me. Sorry for the long rambling post, Im very frustrated I would like to know some of you more experienced peoples opinions on forcing practice when you are physically exhausted. Any suggestions on getting the most quality out of a little time with the bass? I wish I could practice bass at work instead of just talking about.
