> but whatever you end up in you will ultimately have to do work you don't enjoy from time to time, or play politics to keep everybody happy... or deal with a coworker you don't like.

This also applies to you if you're a business owner. Just replace the word "coworker" with "employee" or "customer" (or "partner")

I think the point the person you replied to was trying to make is that you should treat yourself as your own business. Your employer-employee relationship is the same as any other business-business relationship. You're basically selling your time and you should continue to do so for as long as it is beneficial for you.
