business plan

[Obdia Whitmore]

I was wondering if I should have a business plan or not? If yes, could someone explain why? 

[J Scott]

What are your goals?

What is your detailed plan to achieve those goals?

What do you need to accomplish those goals?

How will you get those things you need?

What are the risks?

How will you mitigate those risks?

As long as you know the answers to those questions inside and out, you don't need a business plan.  That said, most people don't know the answers to those questions and that's the purpose of a business plan.
