To be or not to be a musician?

This is a question which appears at some point in a musician`s life.

Each of us knows to enjoy a successful performance, admiration, competitions awards, recognition, a strong motivation or a clear goal in our career. But how do we overcame the moments when we are facing with stage fright, critiques, mistakes, memory slips, lack of motivation or a way without perspective in such a competitive environment? 

A career in music requires many sacrifices so we need: passion, motivation and perseverance to go further, especially in the hardest moments.
