"Say you played 10,000 notes today, and you are thrilled because 2,000 of them were simply amazing! Unfortunately that means there were 8,000 mediocre notes that nobody wanted to hear. Congratulations for the good notes, but sadly, it is the 8,000 mediocre notes that tend to be habit-forming. The majority rules. Try to deliver 10,000 great ones!" - Arnold Jacobs
Remember King Midas? Everything he touched instantly turned to pure gold! Why not have that mindset? Put on an imaginary crown and a royal robe the next time you enter your practice room. Tomorrow as you open that trumpet case and pick up your gold-plated Midas trumpet with its gleaming gold mouthpiece, think about your treasure trove, boatloads of valuable golden doubloons!
You have no notes to waste. Make it your practice to make them all count.
