Don't stop creating. Ever.
The hardest part of being an artist is finding a way to muffle the inner critic and let your imagination flow. The best way to do this is by doing it EVERY DAY. Even small efforts go a long way if we do them often enough. Just keep at it and it'll happen. If you can find ways to keep it fun, it'll soon become a habit that you'll crave. Those habits that are actually good for you are the one worth feeding.
