Law of the Minimum: "The worst potential competition for any organism can come from its own kind. The species consumes necessities. Growth is limited by that necessity which is present in the least amount. The least favourable condition controls the rate of growth."

Frank HerbertWeโve lost something vital, I tell you. When we lost it, we lost the ability to make good decisions. We fall upon decisions these days the way we fall upon an enemyโor wait and wait, which is a form of giving up, and we allow the decisions of others to move us. Have we forgotten that we were the ones who set this current flowing?
