IDK, I think that advice has aged pretty well. Probably should have done it then. Oh well. Hoping the dev suppresses the sunk cost fallacy and realizes that doing it his way just isn't going to work. He's going to have to accept guidance from people who know how to recover from the sort of situation he's in.
Right now
Komisari is at the bottom of a deep hole. He has convinced himself that the best way to escape is to dig a stairwell out of the sides of the hole. Meanwhile, there's a guy at the top of the hole who just got out of the hole next door and has tossed down a rope ladder. Fearing the ladder will break midway up, komi is refusing to use the ladder option. And he keeps trying to dig his way out. What he can't appreciate from his current vantage? The dude who tossed down the ladder is covered in mud from trying and failing to dig his own way out.
How much longer do you want to remain in the hole clawing at the sides before you trust someone else and do something uncomfortable that wasn't your idea and sounded crazy to you?
Trust me bro, you need to put the project on hold, take the pressure off of yourself and get some help. When you've got your head screwed on straight, THEN come back to it. You will finish in days what is currently taking you years. It's going to sound crazy to you; but that's only because you're not thinking clearly right now.
Anyone telling you to do it a different way has no idea what they're talking about. Oh. I would avoid the temptation to try a middle of the road option. "I'll take time off as soon as I get this next update out." That is NOT a good strategy and will make things so much worse. You are not operating at your best right now. Unless you are St. Paul or something, you are not going to have some kind of awakening after releasing the update. No. Things are going to get so much worse. All the ways you've been thinking your life will get better once you get this out... Once it's out and you see how nothing has changed? Oh boy. That is a dark fucking place buddy. The tidal wave of anxiety you are setting yourself up to endure is not something most people come away from unscathed. When you release this update, you want to be sound enough psychologically that you are ready to endure a shit load of criticism. Because I will be very surprised if that's not exactly what happens.
If you're on firm footing, you won't care. You'll just be happy you've learned what you needed to learn and been humbled. You'll be too busy looking forward to the future to care about your past fuck-ups the way you do today.
I have been exactly where you are. Here's the rope ladder. Stop digging. Get climbing.
