This is the true joy in life, the being used for a purpose recognized by yourself as a mighty one, the being thoroughly worn out before you are thrown on the scrap heap, the being a force of nature instead of a feverish little clod of ailments and grievances complaining that the world will not devote itself to making you happy.

It’s impossible to be involved in all situations, but there’s no excuse not to be involved in something, somewhere, somehow, with someone. Make an ounce of difference.
