I've been thinking about this sometimes. Often, when I get in a stressed situation (although I don't often get in a stressed situation), I just remember that in most cases, nothing has actually physically changed since the last time I was in a more peaceful situation. It's mostly just emotions and ideas. When I realize this, I find it really hard to actually get stressed.

On a just slightly related note, I became fascinated about how weekends feel so different from week days, even if I in the weekend sometimes wake up after school would be finished on a week day. The rest of the day is technically the same, but the fact that I remember being at university earlier that day completely changes my feel of the day.

I really enjoyed your write-up.
