Like the gardener, a leader must take responsability for what he cultivates, he must mind his work, try to repel enemies, preserve what can be preserved and eliminate what cannot succeed.
There is about a particularly beautiful tomato plant, how I coaxed it from a tender seedling to a robust plant that produced deep red fruit.
But, then, either throught some mistake or lack of care, the plant began to wither and decline and nothing I did would bring it back to health.
And it finally died....I had a misture of feelings: I did not want our relationship to go the way of that plant, and yet I felt that I had been unable to nourish many of the most important relationships in my life, sometimes there is nothing one can do to save something that must die.
