When I put my head on the pillow at the end of the day, I want to go to sleep peacefully. It’s okay to occasionally get excited or nervous about what’s the next day will bring. Perhaps I’ll be hosting a training to a broader audience, or I’ll get to meet a person where we’ll decide on something that affects my future. It’s a healthy type of stress as long as it’s not negatively affecting my sleep for days in a row. However, I don’t want to keep thinking about a task that’s not finished or how my code will behave if the demand in Asia will cause a peak while I’m sleeping in the European timezone. I also don’t want to think about how I should have behaved differently on a specific occasion. I certainly don’t want to be bothered with the thoughts of how I risked my money on some specific financial asset
