This diagram is too good not to be shared:

For a couple of weeks (or months?) now, I have been thinking of a way to use what I know to generate additional stream(s) of income. I have been reading a lot of questions and answers in Quora (which I really recommend because of its very high quality content) and found the diagram above.

The problem is identifying that one idea, concept, skill, talent, or asset that falls within those circles. Also, it is not really easy to determine if you are "good" with something, or if that something pays well. Nonetheless, hope this proves to be a good tool in my (and your) introspection.
