There is a fountain of youth: it is your mind, your talents, the creativity you bring to your life and the lives of the people you love. When you learn to tap into this source, you will truly have defeated age.
Getting ahead in a difficult profession requires avid faith in yourself. You must be able to sustain yourself against staggering blows. There is no code of conduct to help beginners. That is why some people with mediocre talent, but with great inner drive, go much further than people with vastly superior talent.
