Ideals are Opportunities in Disguise

Your story about your mother's dog grooming business reminded me a lot about some discussions I've had with my brother in the last year or so. He has a car detailing business in Perth, Western Australia, and he really is just the best in town.

But he can't expand because to expand he needs to hire people, and he just can't hire people that will detail cars to his standard. He does it to that standard because he is passionate about car detailing, not because he wants to make money, and it's just hard to find other people that are equally passionate.

His solution is that he is going to try selling detailing products to other detailers, which is quite similar to your mother's solution.
