The bulk of my nest egg comes from equity. As you grow you find that the more of a generalist you are the smaller a company you should be at to maximize your impact.

As a company grows the roles get pigeonholed further and further, diminishing the value of your generalist skillset. The main antidote to this is to be higher up in the org, but that usually doesn’t happen organically over a generalist career (you have to create those jobs for yourself).
