I used to go through this with music. The white-hot process of creating the thing is intoxicating and fun. Better than drugs.
But when you finally complete the songs, or novel, or whatever; what you have in front of you is something cool. Rough, but cool. You created this fucking thing that didn’t exist until you gave birth to it!
Then you step back and realize, Wow, this is a lot of shit. How am I ever going to get this to a finished state?
There’s only one way, son.
Pull up your big-boy pants and start grinding.
