"Act Like an Investor. At the end of each week, ask yourself the following question: Did our actions this past week increase value? What was the ROI on your time spent this past week? If you go 2 weeks in a row or 2 weeks in a month without a positive ROI on your time spent, you’re clearly doing the wrong things."
I feel like this is just good advice for life in general.
Part of me recoils at treating all of life in this way and I think it can be taken too far but at it's heart I think it's good advice.
Obviously quantifying life can be tricky, and it's not possible for every week to be fantastic, but the general principal of regularly assessing it to see if it can be tweaked or improved, and seeing if you're basically happy with it is a good one.
Not everything should be viewed as an investors decision. Passion and determination help to take decisions an investor wouldn't make. That is why you are CEO.
