“We specialize in residential and commercial construction, remodeling and maintenance.”
We all know that’s not how specialization works.
If you want to be a specialist, you have to pick your thing.
Your thing is the reason people call you instead of someone else.
If you’re going for mitral valve surgery, you want a surgeon who is the best at replacing heart valves. It doesn’t really matter if they have a long history of successful hand surgeries.
If you become a catio design-build specialist, people call you to design and build catios because it’s your thing.
Focus on what you do best, and say no to the rest.
