Diversifying portfolio does not necessarily mean diversifying skill set. It only means offering the skill set to more people. I can work for you, but remote, 10hrs a week, then another 5 hours at someone else’s location, and so on…

Think also about the one shot services you can offer. I can come, do this for you, and then you never have to worry about me. No payroll, taxes… businesses like that a whole lot.
