Practicing the guitar- words to banish

I tell my students that there are two words that I must banish from my studio. They are NOT ALLOWED. Those two words are "I can't." You can make mistakes, you can have difficulty, you may find it almost impossible, but you may not say "I can't." There is a simple reason- those two words mean that I will not try. Any other words may say that everything is not coming easily, that work is required, that concentration and analysis is required, that slow practice, and deliberate thought may be necessary to work something out. You will learn something- how hard it is to start something new, how to train your fingers and your brain to do something, how to work up speed so it becomes almost a reflex, rather than a deliberate process, how long or slow it is to learn something new, how hard something at a higher level is when it is attempted at first, but then- the thrill of accomplishment, the unbelieving "well last week that was impossible, but now I'm doing it." "I can't" will not allow any of the positive things to happen, so I urge you to banish those words from your thoughts and speech. Go ahead, wrestle with it if you have to, but do go ahead. Best wishes.
