Success is not giving a hoot. If you can be a 45 year old cat woman playing in front of 3000 people, totally uninhibited, then you are succeeding. Because if you are able to do that, you are in the present moment, not caring about what anybody else thinks. Not worried about their judgements or how you think you should be coming across. (ok, so I was a little worried, so not 100% successful, but I continue to strive to be free of this nonsence)
When you have that presence of mind in front of animals, that is when you are succeeding.
