Don't worry about the times when you lose your quilting mojo. Give yourself grace, do something else for awhile and trust that your zeal will return. It always does.
Buy an iron that doesn't leak. Your skin is worth that $30. But you can buy a $4 iron just as good at the thrift store sometimes. Just use the iron because wrinkles matter. So does accuracy.
Go for excellence, not perfection. Excellence is attainable, but perfectionism stunts growth.
Sometimes it's the people you'll never meet who appreciate your quilts the most. Keep making quilts for the love of quilting and the comfort of others.
