Just as the actor accepts whatever role he is given and performs to the best of his ability,
in the same way taking up responsibility for one's life is to accept and honor the role so that the performance is the best under all circumstances.
The result is that time and resources are utilized to bring maximum benefit.
Each day remind yourself that you are a good actor who brings out the best of whatever role you get.
Instead of thinking of what you don't have start using in the best possible way what you have.
