Motivation and willpower are a mirage invented by self-help books and successful people that do not know the reason of their success. If you rely on motivation, you'll find that you are physiologically very motivated towards some things, like eating junk food, sitting on your arse, playing videogames and watching porn.
Motivation, habits, addiction, are all parts of the same mechanism. What you need is habits, and an environment that is conducive to those habits. Or external forces that push you towards your life goal.
I am not motivated to work 6 days a week on my startup, not to waste my days playing video games or having a healthy sleep schedule. I have, with a lot of pain, created habits around those, so it's easier to do the work that not. I cannot wake later than 8am now, so at 9am I'm at my desk. I have blocked distractions in the morning, so all I have to do is work. I am broke, so I keep at it. And slowly, I start to enjoy the routine. We all enjoy the routine, motivation is a short-term fix that inevitably always returns to the routine. You don't need it.
I hope this rant is useful in some ways, I didn't mean it to sound like that, but alas. I also have ADHD, so motivation to me is but a fleeting idea.
AI as a co-designer makes it more fun too. Somehow AI is capable of more humor, creativity, and wit than me. It's been doing most of the writing.
Now I just wish I had better artistic skill. I probably have enough, but I'm not at the age where I can spend 4 hours on a single scene.
Hope you get better soon.
I also like having money, so i'm generally motivated to work to get money, though I don't always feel motivated once i'm at work, I feel more obligated once i'm there.
The things I feel unmotivated about lately: social media, and administrative tasks
when things are comfy and convenient i find myself slacking. having accountabilities and responsibilities forces me to perform and compete whether i like it or not. i hate it, a lot, but it keeps me alive. capitalism meets stockholm syndrome.
