To keep your marriage brimming, With love in the loving cup, Whenever you're wrong, admit it; Whenever you're right, shut up.

If something doesn't work, you have to admit it. Always try to find what's going right and what's going wrong with your music. If you can, pool your resources and record yourself; do that frequently.
Consistency can be a trap, especially if it leads to being consistently wrong rather than to stopping, admitting your mistake, and changing course.
Admitting errors clears the score and proves you wiser than before.
Wrong is for other people.
Your mind is nirvana.
