I don't know of better way than to let your business give you what you want for your lifestyle. Whether it's a sample business plan for a small business or one where your business gives you a plan, it should tell you what is needed to take you where you want to go and when and how you can get there and it should be in clear simple terms, supported with all the specifics.
Since your executive summary leads your business plan, it is important that you carefully construct this first section. In fact, the executive summary is so important that it is placed directly after the title page, even before the table of contents. Many find that writing this key section works best when completed last. The executive summary serves as a synopsis of all the sections of the business plan. If you wait until the end, you will be better able to write a cohesive and complete executive summary.
