Find a niche that you can offer something that people will want or better yet, pay for. It's better to start small or find a way to enter a market that you can easily differentiate yourself and go from there. Also, you shouldn't try to hide your idea, most ideas aren't unique, it's how you execute them off that can make or break them. So don't be afraid to tell friends and acquaintances and have them give you feedback. There is no easy way to a million but with the internet there are now more ways then ever.
