It's easier to recognize beauty than it is to create it. You're good enough to know that what you're doing isn't good, but not good enough to produce something great. When you find yourself in this frustrating limbo, the challenge is to never forget what got you there in the first place. Remember that thing that got you into the game.
Your love. Your passion. Your taste. That's the reason you're here. You still belong, even if you don't feel like it right now. Your taste can be killer even if your ability is questionable.
Commit to the process and you'll become good enough, soon enough. Put in a volume of work. Close the gap.
