A human being is a part of the whole, called by us "universe," a part limited in time and space. We experience ourselves, our thoughts and feelings as something separate from the rest, a kind of optical delusion of our consciousness. This delusion is really a prison for us, restricting us to our personal desires, and to affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening our circle of understanding and compassion, to embrace all living creatures in the whole of nature and its beauty.
does a gardener only water their flowers after they've bloomed? does a farmer only tend to their crops once they've shown fruit?
so why do you believe you should only write once you've got something to say? why do you only draw once you've got an idea?
if you really want to grow your craft, tend to it faithfully, and not just when you've got the inspiration or motivation to do so.
just as a flower only grows after it's been watered, the words you want to say will arrive after you start writing, the idea will arrive after you start drawing—inspiration will arrive after you start working.
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.
