Perception/„feeling“ vs physical reality. The gap is huge.
Trivial example, I was convinced that the „time toll“ i have to pay around training was very high. Like I was spending an hour or more just to change into sportswear, shower afterwards, and switch back. This perceived deadweight loss always presented an additional psychological hurdle to get off my ass and train. Now that I know that it‘s much less than I thought, it‘s gone.
Similar for cooking.
Like I said, havent done the full analysis yet but I can already highly recommend this practice of recording time at least for a while.
