Most ideas don’t just come out of thin air. They’re the result of knowledge and experience in a special line of work.

When you work in a certain field, you learn about what works and what doesn’t. Entrepreneurs in that field are able to take what they know about what doesn’t work and come up with new ideas to fix those problems.

For example, take a look at Noca. This company was founded by ex-Visa employees to fix the problems with credit card transaction fees. Coming up with good ideas is nothing special; it just takes a little knowledge and a little insight.
