If only such a thing were possible

But then you worry if you did a good enough job at it...

I stress on these tasks rather than completing them because if I don't have these tasks to stress about, I'll have to stress about the much worse tasks waiting just behind them in the queue.

What if I come close to finishing it just to add more work?

What worked for me was to have someone hold me accountable for missing work

But how?

Help I can't do the task

Thanks! Just reminded me that I had a relatively simple task to do that would have been weighing on my mind at 2a.

Now the other tasks on my mind are "perpetual tasks" or otherwise aren't so simple to complete, like finding a new job. So uh, how do I stop stressing about those tasks?

What is this heresy

I know it's a meme but that's terrible advice.

If you finish all the tasks most employers will just give you even more tasks for next week.
