In life, people only pay for solutions. This is what you should consider before setting up a business.
How will my product or services be of help to people?
How and where do I get this people?
What are their needs?
How do I make them my product/service addict?
Onces you're able to fix those questions then you're good to go.
Remember, people primary concern is what is in it for them and not who you're.
