Eventually you have to accept that you're a good composer right now, the best you'll ever be, today; because otherwise, if you insist that through study or practice you can become a better composer tomorrow, then you'll want to start the piece tomorrow, and tomorrow by the same logic tomorrow again, and time escapes, and you never compose anything. Zeno's Paradox of Creativity: you have to start the piece today, or you never will. You actually have no choice. You are the best you'll ever be.
Perhaps the essential distinction is that between perfection and completeness. We'll never be perfect, but we are always complete.
