On the subject of finance, you need to produce realistic financial details. How much money will the business require? What are the expenses required? How much tax will you need to pay? What are the profit margins? Do you stand a good chance of achieving these sums, and how? Finance plans should include income statements, cash-flow statements, balance sheets and profit analysis. This should form a big part of your business plan, in order to convince the vendor or bank manager of your credibility.
Did you ever stop and think what a unique position you're in as a business owner? I don't know of any other way you can have as much control over your success than owning a business. When you work for someone else, you are totally at their mercy as to what your future may be like. It doesn't matter whether it is a private business you work for or a large corporation. Your future is in their hands. The only thing that might qualify other than owning a business would be to inherit or win a lot of money that would give you everything you want in life.
