"I'm always busy but I don't feel productive with my time"
Why? "Because I get distracted by email, refactoring, slack, .."
Why? "Because I don't really want to be doing any of this, but I feel like I should be at my computer trying to force myself to do it."
Why? "Because I have a job and therefore some responsibilities, and I wasted a lot of time last week so I guess I need to get things done this week"
Why? "Because I'm sitting at a computer at home, surrounded by nobody, writing code for projects I don't really believe in, that are being mismanaged outside of my control, and what rewards there are (salary) are totally decoupled from the work, and I have lots of money saved up from doing this anyway but the modern world makes no sense and there's nothing I really want to be doing so I guess I'm working."
... ah, you say, you can't work because you're burnt-out and depressed. Yeah, probably. But I mention this to make the point that: if you can't focus, perhaps you just _don't want to be doing whatever you're doing_. It is sometimes hard to admit that in this modern world where you're supposed to be a hard-working adult. But you don't .. have.. to be employed, or working a 9-5, and for many people it's deeply unnatural, I think, to be doing this your whole life day-in and day-out.
