"Efficiency" is bad for your health, and your learning

I used to stress a lot about the “efficiency” of how I was using up all the minutes in my day. I’d to cram in as much as possible into time. eg. read on a 10 minute train, write code in the half hour before bed, etc.

While I stressed about it a lot, I never found that I did the “10x” things I read about that were supposed to emerge as a result of this extra “efficiency”. For example I have only finished one of the three side projects I started in 2016, despite promising myself that those wouldn’t take long.
