Substitute any dream for the word “artist”…
“Give yourself permission to be a beginner. By being willing to be a bad artist, you have a chance to be an artist, and perhaps, over time, a very good one.
“When I make this point in teaching, I am met by instant, defensive hostility: ‘But do you know how old I will be by the time I learn to really play the piano/act/paint/write a decent play?’
“Yes . . . the same age you will be if you don’t.
“So let’s start.”
~Julia Cameron, The Artist’s Way
