You think aiming for some degree of excellence is better than succumbing to perfectionism?
On the contrary, there could always be something else that could’ve been done to enhance the quality of your work. Your work could always have been better if you did this or that. Aiming for a certain level of excellence will make you unable to leave now anyway regardless of the quality. That is why everybody hates perfectionism. When you aim for perfect from the start, you don’t keep trying to increase the quality to meet a certain standard. You aim for everything to be epic from the start to the best of your ability. In this case you will never have a hard time leaving the piece of art, content, or your work, because even though it’s not the best, or perfect by any standard, you did everything in your power from the start to make it not suck. You went all in. And now you can leave it without feeling bad about it. Being at peace with your work is priceless, and is always worth the effort.
Stop denying yourself reward. Don’t turn your creative endeavor into labor.
