I have been thinking about that issue with regard to you since:
I have the perspective that I’m a universal knowledge creator and all problems are soluble. So I have profound optimism that I can learn and solve anything, with enough time. I can certainly learn way more about universality, knowledge creation and the nature of problems. But I like what I have read about it so far and I think it’s a positive mindset to have.
You describe it as stressful, and problems can be stressful when there’s a time limit. But for most things there isn’t that hard of a time limit. So maybe take your time and be calm and confident that you can solve it eventually. You might want to set off the problem to later and power-up first, so related to time again. So no need to be stressed.
