I would listen to something on the radio and try to tap out the melody, then the harmonies.
You should make something. You should bring something into the world that wasn't in the world before. It doesn't matter what it is. It doesn't matter if it's a table or a film or gardening-everyone should create. You should do something, then sit back and say, 'I did that.'
A tree is known by its fruit; a man by his deeds. A good deed is never lost; he who sows courtesy reaps friendship, and he who plants kindness gathers love.
