So, you want to start a company.  Well, the first thing you do is you should write a business plan, and so I did that.  I wrote about a 30-page business plan.  I wrote a first draft.  In fact, I wrote the first draft on the car trip from the East Coast to the West Coast.  And, that is very helpful. You know the business plan won’t survive its first encounters with reality. It will always be different. The reality will never be the plan, but the discipline of writing the plan forces you to think through some of the issues and to get sort of mentally comfortable in the space. Then you start to understand, if you push on this knob, this will move over here and so on.  So, that’s the first step.
