I'll preface this by mentioning I'm not a psychologist. I'm somebody who grew up with ADHD and possibly autism and never really understood it. This is just what helps me now.

What I wish I learned as a kid is to set much smaller goals. Same goes for programming. Instead of programming a whole game, maybe try slightly modifying a mod, like replacing an icon or adding an option.

The other thing is to recognize the things you've accomplished, which includes small steps like "watched a tutorial", "learned the difference between some game engines", "installed an engine and got a block to show up on the screen", etc. It may not immediately look like it, but those steps have a lot of value.

Beating yourself up over the things you haven't done is more likely to set you back, in my own experience.

I appreciate it, and that's probably the right move. Unfortunately, I know that I wouldn't want to pay that, knowing that I'd be helping feed Reddit.
