Having certain limits - not too many, but certain limits on an ability to tell a story - makes us work harder, me and my writers. Sometimes I watch a giant movie with a $250 million budget and I think they feel kind of bloated, and that if they'd been leaner and meaner they might've had better storytelling.
You will never learn anything new unless you are ready to accept yourself with your limitations. You must accept the fact that you are capable in some directions and limited in others, and you must develop your capabilities.
