I keep seeing this theme on HN that more money = better. That is not always the case. Now she is working 1 on 1 and not trying to work on multiple people at once. Not everyone is chasing a dollar. I sell chicken eggs for no profit but I like the chickens around and I get some eggs. But the egg farmer charging 5$ actually makes some profit. So if the clinic only makes 150-200k but brings happiness to them that is way more important then money in my opinion.

What about all the expenses she can claim? Does the business pay for her car? Does she work out of the home?

Does she have somewhat unlimited PTO? What’s it like having no boss?

Rent is 12k/yr. Insurance is 2k per year. Software is 500 per year.

Cleaning supplies are trivial.

I can't think of anything else. We are considering getting someone to call insurance companies in the future. 40k/yr, but currently she does it.
