"Let us consider your mind for a minute, because it can be the single biggest problem when creating artwork. Rational thinking may say that you have to do 'good work', whatever that is, to justify the time you spend, and then you should show and sell your work for it to have value. Get off that channel. See the worth in the process itself. You are participating in active meditation - think of it as exercise of the spirit. Your work and your spirit will grow together regardless of the results."
