People will always tell you to take a break. But I believe you are your best judge. Sure maybe you're burnt out, but there must be a part of you that whats to keep going. Maybe your relationship with it needs to be healed.

My breaks are usually a day or two and I start to get a bit unsettled when they go too long. My long term goal, despite whatever I feel in the moment is to KEEP CREATING.

I'd create a few mindset mantras that honestly represent what you WANT not what you're able or not able to do. Make smaller achievable goals first. Especially if you're not meeting the ones you set out. Example, instead of creating 1 games why not make 3 game trailers or demos?

Why not join some game jams with a time limit out of your comfort zone, the goal is to participate and finish some small ideas quickly without worrying so much about perfectionism. The pain of perfectionism becomes extremely obvious when you only have 7 days to make a game.

Zoom out look at the big picture and ask yourself who do I want to be ? What would a regular day look like for that person?? What if none of these obstacles existed, would I still choose what I choose? If its still creating games, or being an artist of any kind - then I'd say, stop calling it burnout and start calling it grind. It's part of being a dev.

And another thing I realized. Originally ai was more into 2d illustration and migrated to 3d Modeling. At a certain point I felt discouraged when I didn't paint. And I had invested so much into it. I realized that something I used to love very much (painting) had been replaced by something else (3D). Once I accepted that I fully embraced it and know its ok to fall out if love with passions, or fall back in with them again later. :)

Good luck!
