In the end, we shall recognize our song and sing it well. You may feel a little warbly at the moment, but so have all the great singers. Just keep singing and you’ll find your way home.
I love the balls-to-the-walls rule-breaking approach the Beatles had in the studio (which I emulate), although I don't try to make my songs "sound" like their songs. But every time I crank a knob of some piece of equipment, or plug an instrument into the "wrong" amp/effect, I am channeling the Beatles.
Truly creative people care a little about what they have done, and a lot about what they are doing. Their driving focus is the life force that surges in them now.
If you are not living with a whole heart now, the end of the world poses no threat; your life is already gone. Life is only as valuable as our presence to enjoy it. To miss the beauty of the moment because you are preparing to protect yourself from the next one, is to trade a precious gem for a cheap trinket.
The difference between famous creators and struggling artists is that the creators know that improving the lives of others deserves the highest reward.
