Coaching baseball, when doing drills, the time allotted on your priority list for practice should not be compromised, even if it is not going well. Extending one drill will ultimately shorten or eliminate the time planned for another. Even if you are frustrated by the effort at the time, go on with your time allotted activity. For example if you are doing a multi group drill like linked here, you will often find, when you return later that learned more that you think. It’s best to stick with the play.
