Substance is enduring, form is ephemeral.

Preserve substance; modify form; know the difference.

The closest thing to a law of nature in business is that form has an affinity for expense, while substance has an affinity for income.

Success follows those adept at preserving the substance of the past by clothing it in the forms of the future.

If you go back to the first single-cell form of life, it clearly possessed the capacity to receive, to utilize, to store, to transform, and to transmit information.

The problem is never how to get new, innovative thoughts into your mind, but how to get old ones out. Every mind is a building filled with archaic furniture. Clean out a corner of your mind and creativity will instantly fill it.
