Business Planning its all in your personality

I have over the years seen some marvelous Business Plans and well some pretty ordinary ones as well.

Here is my tips:
The good ones:

1. Written by the owner with a clear vision reflecting their values and personality
2. Clear and Simple
3. Financials are done after the Marketing Strategy

The bad Ones:

1. Written by Consultants
2. Detailed and complicated
3. Destroyed a forest of trees
4. Cost a fortune
