Business Plan Tip: Keep it short.

I had a guy -- an experienced businessman -- tell me that business plans are supposed to be at least 60 pages long, and preferably 80.  Baloney.  A business plan only needs to be long enough to cover the essentials:  Problem, Solution, Demand, Business Model, Marketing, Competition, Funding, Management.  If you can do that in 20 pages, great.  Anyone who reads your plan will thank you for being brief.
