Commencement Day has a sobering finality in that it's the end of the prescribed path.

Every moment was a precious thing, having in it the essence of finality.

On Day One, a start-up is a faith-based initiative built on guesses.

The music and movie business has been consistently wrong in its claims that new platforms and channels would be the end of its businesses. In each case, the new technology produced a new market far larger than the impact it had on the existing market.

Any dispassionate observer would recognize that on Day One, a start-up has no customers, and unless the founder is a true domain expert, he or she can only guess about the customer, problem, and business model.

We are past the end of things now, but I don't want to leave.
