I am working to show my students that you should perservere with difficult tasks.  Practice more than once, take a break but return.  

I am just learning the drums, but…  Here is the most difficult piece I am playing tomorrow.  I took a video of my practice session to show the kids how many mistakes a new learner makes, and that it is OK to be less than perfect!

Not certain who said it first, but both my sons exited the Griffin-Capital band tradition with this mantra:  Practice Makes Better.  (note: link will open in a new window, with a youtube video)
 
Hope it is true for me, too!
