I saw the Stones three years ago at the Wiltern Theater in L.A. and that was mind blowing.
You must accept that you might fail; then, if you do your best and still don't win, at least you can be satisfied that you've tried. If you don't accept failure as a possibility, you don't set high goals, you don't branch out, you don't try - you don't take the risk.
I went to the Academy and studied with Stuck who was then a big man. But didn't interest me. I didn't know that before me there was Kandinsky and Klee who had also studied with Stuck. He had a good name at that time.
