While the idea of being the lone entrepreneur is seductive, the reality is just as you outlined, people working 9-to-5 while doing something else.

This shouldn't discourage anyone, rather, its just a pragmatic way to build systems that enable you to break free of the work-for-someone-else drudgery.

Success doesn't come overnight. It shows up with lots of luggage, an in-law, and a small piano that needs to be moved up to the apartment on the hill.

Get to work. It can be done.
