True, you do need to have some of the adjacent skills necessary to even get your foot in the door with these side hustles. The due diligence ones were possible because I know how to read financial statements fluently enough for clients to take me on despite not having the precise skills required to do them. I didn’t need long to hit the ground running.

All the same, the most financially rewarding side hustles tend be those that require some skills investment. Everyone can do easy side hustles, and the result is everyone applies to do those easy side hustles, driving the rates down.
