In the experimental episode (literally recorded on the road), Neil discusses the differences between being a business builder and a business investor.
Neel has long tried to do both, but has recently realized that means he's only doing half as well in each field. He thinks it makes more sense for him to pick one and make the other more passive.
Since it's rare to find someone who can excel in both building and investing, it makes more sense for people to pick, and either is good, but it probably makes sense to lean into what you enjoy.
