Flow
If you see me playing overly complicated games, that means I’m doing great. That means that I have enough mental fluidity to spend a few dozen hours managing the 15th century British Empire in Europa Universalis IV. Or that I’m refreshed enough to tackle the menacing bosses in Cuphead. Or that I’ve got grit to build and rebuild and rebuild and rebuild the assembly lines in Factorio.
It also means that some unclenching has occurred. Namely, I just finished a very long and tedious piece of work related to my game, and that released a lot of tension. Even though I still haven’t fully recovered from sickness, I’ve done my first tiny workout today. In other words, everything is going really well.
Oh, there’s another thing you’ll need to maintain your flow. Water. Stay hydrated.
