Good CEOs know that they should double down on the projects that are working and put more people, resources, and attention on those rather than get every single project to the point of “not failing.” Similarly, good investors know that helping to identify and grow a single start-up into the next billion-dollar company is worth dozens of other investments that lose money.
Interesting idea - invest your time in the strongest teammates and dont spend too much time on less performing ones. Reminds me of the 80/20. At the same time this might lead to a compounding effect from the "weaker" employees where they.become team detractors. Then you have to fire them most likely becase unless its an easy fix ypu just made the performance worse by actively showing your values to the less performing employee.
