While I still recommend the business planning process, I caution you to realize that a beautifully crafted document does not always equal business success. I've worked with many entrepreneurs who successfully launched without a plan, and some with beautifully written plans that never materialized. You and your business idea are unique. Your planning process will be unique as well. Be wary of one_size_fits_all advice or pronouncements from experts about how you should proceed.
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?
