We have found that when entrepreneurs dedicate their time to planning their business, not only do they save money by avoiding mistakes, they are also more likely to succeed. A good business plan requires the entrepreneur to address all the challenges he or she will face and visualize exactly how he or she will achieve his or her goal. Through this process, the entrepreneur will improve his or her understanding of the opportunity ahead and better prepare him or herself for success. This is why banks and investors almost always require the entrepreneur to develop a detailed and professional business plan.
