1, The best business idea is to find something you can get for little or no money, that you can sell for more.

2, The second best business idea is to create a problem or find a common problem, find/have the solution and monetise the solution.

3, The third best business idea is to take a traumatic experience/traumatic event, you have been through, learnt the lessons from the experience, turn it into a business idea and use it to help others.

4, Fourth best business idea and my favourite, is to find a solution to a common problem, give it away completely free, as an act of Love, helping advance the human species, the Inventor of the internet/WWW, gave it to the world completely free.
