What if the best thing you can produce meets only with rejection or indifference? That feels bad. It’s in some ways the worst feeling of all. You tried your hardest and they didn’t like it.
On the other hand, it’s still your best work. It might not be for the person or people rejecting your work right now. It might be for somebody else. You might not have shown your work to those other people yet. They might be crazy about what you’ve done.
As always, if your best work is met with rejection, then produce better art. You know you can. You’ve come this far. Why not go the next step? It’s just one more step.
What you should never do is conclude that a rejection of your best work is implicitly a rejection of you and everything you are. We’ve all made that mistake at one time or another. The two have nothing to do with each other. You’re still who you are and that’s a creative being striving to produce and show your best work.
That’s not such a bad kind of person to be.
