Another point of contention is how optimistic you should make your business plan. The problem with making over-optimistic predictions and plans is that these plans could well go wrong. Unforeseen circumstances can always put a spanner in the works. Therefore, it's wise to err on the side of caution when it comes to devising your business plan. Indeed, it's wise to predict conservatively and prudently when it comes to assessing the possibilities of future targets, sales and profits. A worst-case scenario will always prove to be less of a shock than one that raises expectations too high.
Another great resource for writing a business plan is your local Small Business Administration center. Most major cities have these types of small-business assistance resources, either in a brick-and-mortar office or online. These SBA websites almost always offer comprehensive resources for start-ups like a sample business plan, business plan development ideas, events, counseling and training services, and local resources. Check to see if your SBA website has free, online planning webinars. Even if you local chapter doesn't offer them, you can easily find a website in another region that does. These online seminars are typically self-paced, 30-minute long resources that help you understand the components of writing a business plan (which provide much more insight than a simple sample business plan), and may be offered in a variety of languages.
