I said that you need a customer base. The problem, of course, is that customers are needy. To maintain a customer base you have to be willing to work and you have to deal with people every day.

There will come a time when you get tired of playing the customer service game. You might want to quit. That's fine - I'm not going to discourage you. Some people just don't find the work pleasant enough to justify doing it.

But before you quit, keep in mind that if you're good, and if you've chosen a company with good products, in anywhere from 2-10 years you can semi-retire and live very comfortably.

But also keep in mind that there's no guarantee you will succeed. You have to work hard and you have to be good to your customers and you have to build your network by talking to both friends and strangers. Not everyone can do that.
