If we don't plant the right things, we will reap the wrong things. It goes without saying. And you don't have to be, you know, a brilliant biochemist and you don't have to have an IQ of 150. Just common sense tells you to be kind, ninny, fool. Be kind.
I am convinced that courage is the most important of all the virtues. Because without courage, you cannot practice any other virtue consistently. You can be kind for a while; you can be generous for a while; you can be just for a while, or merciful for a while, even loving for a while. But it is only with courage that you can be persistently and insistently kind and generous and fair.
