There is a very simple way to think about this.

1. What are you good at? What skills do you have? What do you have work experience in?

2. Of the problems you have found which ones do you have subject matter experience with?

3. Then talk that about that specific idea with people around you. You will start with A by the time you talk to people you will be at Z

4. You need to make sure the problem is a large one and something people actually want. There is a difference between wants and needs.

If you say: Customer needs something
You have to educate them on why they need it which costs $$$$

If you say: Customer wants something
You can put a wall between them and they will go and buy it

Happy to chat further and dumb things down for you.
