There are many roads to succes, and I think a sort of single-minded ruthlessness (or, yes, more charitably “intensity”) can be a fairly simple one.
But I believe that that ruthlessness is the source of a lot of suffering caused by, and happening inside of, companies.
I think it’s really important to try to find a way to be successful that doesn’t just involve being obsessive and single-minded, and if you’re unwilling to do that you’re letting yourself off the hook in a bad way.
