The next day I told my manager that instead of the promotion I was due, I would take Fridays off for the same salary. Somehow, when I had two days off I found it easy to overwork on the weekend, but when I decided that every week had to have a 3-day weekend, everything changed. I started spending hours and hours at bookstores and cafes, and walking around SF and Berkeley.
Of course it had a downside. I told my team not to hold meetings on Fridays, but they would forget and go ahead without me. My ego used to get bruised at my dispensability!
I'm sure I left many career options on the table, but gained many life options. So much so that I eventually started working only six months a year (did it for 19 years), and picked up a PhD (starting at age 42) during those years.
There will always be relentless deadlines, but there has to be enough whitespace built into a life.
I have retired now, but I still wake up wanting to write code or learn something now.
