If my memory serves me right, you were crying that, because you spent 5 hours making a livery and your brain itching about the lost revenue you could have been making grinding, and then somehow blamed polyphony for bad game design.
I responded by saying this mindset is cancer, by applying it to my hobby, and my job. Why do I spend hours making custom 1:64 diecast when it could be doing legal briefs making about 220$ an hour. Clearly, because I ENJOY making diecast cars and because have self-discipline, yes self-discipline is required in order to enjoy life because lots of people ln this world have a cancerous mindset that prohibits them from enjoying anything because they are not adequately "rewarded" by it. This is why so many guys my age have no job, because they feel like they aren't paid well. I decided to study my ass off for 8 years without pay, and now make great pay despite having really bad dyslexia. People think I'm stupid because I misspell things, that just means I have to spend more time proofreading ( for free). I also enjoy my hobbies even though I could be making more work, at first it would bother me, but I had to train myself and refrain from thinking that way.
You should find joy and satisfaction from making your arr, not from the end result. Your mindset leads to people concluding, why do anything at all, we all DIE .
