Step Up and Take Charge

I am at a lesson. Rave makes the same mistake over and over. It is not at the location for the skill I had intended on working on.  It is 'on the way' there.   Do I abandon my plans, step up and make the necessary changes and corrections to stop it? No. Instead I just continue to work on the 'other' issue. The one I set up the lesson to work on.  I have done this at many locations, under different trainers. I think it might be because I am unsure if I suddenly start doing something else my trainers will think I am ignoring what they wanted me to do.  A lack of self confidence on my part.  It is my problem.  Another example is the stop.  I let it slide at lessons. I have got to correct my behavior if I expect to be able to correct my dog's! I am eager for my next lesson to see if I have learned my lesson yet.
