"If I could define enlightenment briefly I would say it is the quiet acceptance of what is." - Wayne Dyer
I once heard Joe Alessi, in response to a question about taking auditions, tell a student that they had to get brutally honest with themselves about what they could and couldn't do on the horn. This is the musical enlightenment that all successful musicians experience. Once you realize what you can and can't do on your horn and quietly accept it as so, you can make a plan for conquering that which falls into the latter category.
This of course applies to what you can do on a podium, in a classroom, as an entrepreneur, as an interviewee, to any pursuit. Face and accept your strengths and your weaknesses with brutal honesty and you too will experience the enlightenment.
