My favorite is when someone says "I hate taxes", and I reply "That is why I'm so busy"!!!!
I figured out a long time ago that every successful business needs to have a niche. So I prepare tax returns in the client's home, with a portable computer, and I have been doing that since 1983, when no one else did that (went on my own in 1980, but prepared by hand the first 3 years). I do not advertise, my business is all word of mouth, and I have all I can keep up with. I also work evenings & week ends (7 days a week in tax season). I can't tell you how many times I ask for something, and the client runs into another room and gets it, and we FINISH.
My Dad used to make everyone come into the office. They would forget to bring something, the folder would go into the hold pile, they would promise to call the next day, and you would hear from them 3 weeks later, after you forgot what the H*** you needed! My system reduces that problem. I let the more organized folks come to me, saves me travel time.
The way I see it, I observed the problem my Dad was having, and figured out a solution that would make the client want to use me. It worked. The only problem is that working inside those two weeks in April just kills me! When the weather is bad, I don't mind so much. Hey, I guess that's why it's called work!
