Every time you play you have energy within you - universal energy. That's the energy that keeps everything together - the planets, the galaxies. Everything.
Inspiration is not inside of us. Inspiration comes from outside. It comes from our spiritual guides and from different energies that are in the universe. If we keep in touch with god and our spiritual guides, just knowing that they exist and they are there for us, gives us the strength to say well this is a bad phase but it's going to end and when it ends I'm going to do something good.
Of course, you have to have a good reputation, especially as an artist, as a musician, so that other musicians would like to play with you.
