Everything on earth is tending to become compact. Gone are those days when a sea beach was described in a thousand words. Today, a similar description is possible with a powerful visual and a string of strong adjectives in only a few words.
A business plan is the first step of starting a business. It is neither easy nor difficult. What is a business plan about? How do you implement a business plan? What do you include in a business plan? What are the'must have's' and 'have not's' of business plans?
The reality is no matter how much you work with things in your head, no matter how confident you may be and how much you think you already have a great vision for your business, there are so many great reasons why you should get it down on paper.
I teach that you should seek to learn from competitors; obviously never copy another business's idea or what they are doing, but you can absolutely learn from their mistakes or see what they are doing and discover ways to improve it. All of that analysis belongs in your business plan: make sure you have your competitors under the microscope and make sure that is a solid chunk of your plan. That is some of the best research and information you will gather about what will make your business successful in future.
