I began to order books on gardening. I studied different gardening techniques and types of fertilizers. I did not have many of the materials that the books discussed, but I learned through trial and error. For a time, I attempted to grow peanuts, and used different soil and fertilizers, but finally I gave up. It was one of my few failures. A garden was one of the few things in prison that one could control. To plant a seed, watch it grow, to tend it and then harvest it, offered a simple but enduring satisfaction. The sense of being the owner of the small patch of earth offered a small taste of freedom. In some ways, I saw the garden as a metaphor for certain aspects of my life. Leaders must also look after their gardens; they, too, plant seeds, and then watch, cultivate, and harvest the results. Like gardeners, leaders must take responsibility for what they cultivate; they must mind their work, try to drive back enemies, save what can be saved, and eliminate what cannot succeed.
