1). Think about what you love to spend time on, and make it the priority goal.
Protect your personal self from the idiots, and create a comfortable environment to do your best.

2). Think about the target market who might need your skills, where they are located, and how to reach them the best way.

3). Think about the negatives that might occur: Limits to skills, problems beyond anyone's control, etc, etc, etc...
Have a backup plan or two.

Then go for it.
Life is short. Life is solving problems.
