Here’s a little exercise for your brain cells. You might want to think about it for a time before replying. There’s no rush. Be as creative as you like.

The exercise is (1) to create a storyline that has the Main Character involved in one or more of the following activities and (2) for that storyline to have a point, a purpose, a goal for the MC:

Buying and selling real estate; property development; cab-driving; private investigations; money lending.

Too hard? Forget the storyline then, how about just a goal for the MC to work towards?
