I could definitely add to this list! On top of everything you mentioned…
(1.) I don’t need a babysitter for my children; nor do I have to rely on daycare.
(2.) I don’t have to answer to a “boss”.
(3.) I don’t have to deal with work-related drama or conflicts with co-workers.
(4.) I have more freedom than with a traditional job because I can choose what I do or do not wish to do.
I have a bunch as well. Saving gas on a commute, improving my social skills/confidence/acting abilities, and in my case strengthening my relationship. I also like making a living with nothing but my own gifts and attributes.
I have to say that I first thought that working with my wife will affect our marriage in a bad way, but I was wrong. We make a lot more money than before, we have more free time to spend together, we make our own schedule and, let’s not forget, we have a lot of sex.
