I've been trying to make a game for over 20 years now. Cant believe i've been so long at this.
I started with Darkbasic (classic now), then an early game maker, i think version 3 or 4 by mark overmans, then i found clickteam and stayed there for a few years before construct classic was announced and i've been here ever since.
I definitely don't have the motivation i once had. Its sad cause at the start i lacked patience and understanding but had plenty of drive, now i have a lot of the understanding ( i often do eventing in my head, or a text editor, and putting them into c3 editor usually works right without much change), but lack the drive.
I think one of the reasons ironically is the bar to entry is so low now. Any game you think of, no matter how unique, you look and its already been made, on sale on steam and done better than you ever could. Ai is another reason i guess. Also i have this terrible thing where as soon as i know i can do something i lose interest in doing it.
I found that when i do get fed up and stop for a week or two my brain suffers. I guess theres nothing quite like the mental exercise you get from trying to solve complex problems of your own creating.
