Sauna is an amazing thing: you may go in there worked up about something or worried, and come out calm and — more importantly — in your right mind again.
For instance, yesterday I was feeling furious at my bank because they paid an instalment of my apartment two months early. I thought, of course, that I’m losing money in interests because I’m starting to pay them now instead of two months later.
Then I went to the sauna (today).
Now I’m thinking, what difference does it actually make if I’m paying for this particular instalment + its interest for x number of months starting now instead of x number of months starting a bit later. I’m still feeling a hint of uncertainty, but logically thinking it doesn’t make much of a difference (the interest rate does change annually but it affects the situation only marginally).
This “enlightenment” has happened so many times that I sometimes feel stupid when I realise I’ve been worrying about something for no reason.
