Talk is cheap. What is accomplished through speaking, and by extension, writing? Writing is a much more permanent medium than speech. It is documentation not only of process, but of life itself. The written word can be reread later. Speech, however, seems never to desire rediscovery. Out of all the great conversations you’ve had in your life, how many of those do you wish you could relive? How many of those were valuable?
Do more than talk. Discourse may be valuable at times, but understand that with speech, you are gambling time. With philosophy, reflection, and other viable pursuits, you are investing.*
*This distinction between gambling and investing comes from two books I’ve read: The Intelligent Investor by Benjamin Graham and The Theory of Poker by David Sklanksy, two great reads.
