The feeling, "this can't be it", is a very powerful form of prayer. It's the agony of the separated self longing for reunion with wholeness. It's the call of your soul urging you to return to your own path and purpose. It's the force of evolution driving you home. Do not try to deny or override your divine discontent. Heed its call. Knowing "this can't be it" implies that somewhere inside you, you DO know what IS it.
We can look at any experience in two ways: through the eyes of lack, or the eyes of plenty. Fear sees limits, while love sees possibilities. Each attitude will be justified by the belief system you cherish. Change your allegiance from fear to love, and love will sustain you wherever you walk.
Every musician I have ever heard has influenced me. I often find I emulate micro-aspects of an artist, and combine it to form something new and unique.
Those who love you are not fooled by mistakes you have made or dark images you hold about yourself. They remember your beauty when you feel ugly; your wholeness when you are broken; your innocence when you feel guilty; and your purpose when you are confused.
If you have to have it, it's ego. If you have to not have it, it's ego. Hold life lightly and it will deliver what you need and release what you don't.
