I was in your position once, the best thing you can do is to take a business course, learn the basics of accounting, marketing, management, finance, law and such.
In NZ there is a few certificates designed specifically for aspiring businessmen.
Trust me, once you have a basic understanding about business, and things like taxation and accounting and marketing you become more confident, you can look at situations and imagine how to capitalise on them.
Knowledge is the key to success in business, especially so nowdays. Just remember you don't need to be an expert accountant, you just need an understanding, the key is that you don't have to have all the knowledge yourself, you can pay someone to do that for you!
I've gone from a net worth of 2k and uncertain... to over 50k and having my own company and I'm constantly learning and achieving. [Still in training though, I'm about to start a degree].
remember if you can think it and imagine it you can achieve it.
