Everybody wants to get the thing done, and of course finishing is important. But it’s not everything. You are going to be in a constant state of unhappy frustration if this is all you’re focused on, and you’ll be depriving yourself of a great deal of joy at the same time.
Learn to enjoy the process of making the thing and you’ll be a lot happier – after all, it’s the only part you have any control over.
Once it’s done and you release it to the world, beyond promoting it, whatever happens is out of your hands.
