"Being a good private equity investor is more complicated than it seems. I would say that there are a few characteristics that are important. If you look at the skill set that you need to ultimately be a successful private equity investor, at least at the senior level, you have to be, in this business, a good investor. You have to be able to help companies perform and you have to have judgment around exiting investments. If you look at the skill sets there, they include some things you can teach and some that you can't."
