Far be it from me to dampen your enthusiasm, but you should give yourself every opportunity for success. That's what the planning part of the process of creating your business plan will do. By the time you have pressed your way through it, you will not merely have some neatly arranged document to keep on file, you will have a working tool that addresses the essential factors that influence your future.
So why make a business plan? I want to show you a totally different kind of business plan. What if you made a business plan that focused only on what you want for your life? You have dreams about what you would like your lifestyle to be, right? Why not make a business plan that could give you those dreams? What would your business look like if it gave you exactly what you want in life. What kind of salary would your business need to give you? Why not build a business plan around that? Decide how much salary you would need to support your dreams and then build a business plan that would show exactly how your business could give you that. Wouldn't it be better to have your business work for you instead of the other way around?
