@AlinaLeonova Ah, I wonder how much of my advice will be applicable to writing, but let me try!
Well, one thing that might be relevant, I've been really into indoor cycling over the past year or two, and I use that time to take notes for the next project or a blog post.
Outside of that, and this may be more useful for projects that involve writing code, but I try to reuse my own work, and existing code others have shared.
For example, I run almost 70 creative bots.

Sounds like a lot! But some of them are variations on the same idea.
And for many, the actual code is just a few lines, because I'm reusing a lot of the existing work I've done over the last decade.
