Only one life to live! We all want to do our best with it. We all want to make the most of it. How can we best get hold of it? How can we accomplish the most with the energies and powers at our command? What is worth while? We all ask ourselves this question when we leave our college halls. But the first years out of college are apt to be anxious, unsatisfactory, disappointing. Time slips away in further preparation, in experiment, in useless or misdirected efforts. The world does not prove to be the same that it seemed to be in the quiet college surroundings. Duty is not so clear as then, nor work so well-defined. Life is harder to handle than we thought. One finds that theories fail, and yet one has not had positive experience enough to know just where the difficulty lies. It is of a few simple things that “my own life has proved true” that I shall speak to-day.
