I suggest you take a business class and study business and management. All business owners and students know you never expect to earn any real profit for a minimum of 2 to 4 years. And upwards of 70% of business fail. I think you need to do some research on business first off to make sure this is what you truly want to do. Then find something you are passionate about and go from there. You have to love what you do.
find a niche and concentrate on the demand that people are after.
