Arrogance, humility and how things get done

The older I get, the more I see how nothing gets done without a dose of arrogance and nothing endures without a large measure of humility. I really get tired these days when I have to rev up the confidence level to an unbearable level just to get something done in my work. And, after its over, I am worn out because I don't enjoy flights into arrogance. I'd rather stay calm, shoot straight, but that won't always get done what is necessary in either the law or in religion. But, I'm having a little more success lately in the religious area with just speaking the truth, staying calm and letting the chips fall where they will. In matters of faith, maybe it is just an illusion to think you have accomplished anything when you act contrary to the way of faith to get it done.
