Ok, it's winter and I am at the local indoor range. I have paid for an hours time and cannot seem to focus on shooting drills. Starting at 20' shooting DA/SA drills and moving out to 60' in 10' increments. Poor results and cannot turn off the radio in my head. I cannot get a short sequence of good shots to end the session on a positive note. Is it best to just quit and come back another day or continue to try to do better ? Am I reinforcing bad habits by continuing ?
