Business plans

I'm starting to put together a business plan and I'm wondering what is key to include if I am NOT looking for funding. I've seen a lot of exhaustive and impressive examples made to sway bankers to give out loans, but... I was lucky enough to come into some money which I have decided to invest in my life long dream of making chocolates for a living... So I don't need to impress anyone with dazzling market analysis, etc. what I need is a cohesive and detailed plan to succeed. I want to have all the necessary parts to get things started without wasting a lot of time on details meant to I press bankers. Any suggestions?
