DEAR sir, good-morrow! Five years back, <br />When you first girded for this arduous track, <br />And under various whimsical pretexts <br />Endowed another with your damned defects, <br />Could you have dreamed in your despondent vein <br />That the kind God would make your path so plain? <br />Non nobis, domine! O, may He still <br />Support my stumbling footsteps on the hill!<br /><br />Robert Louis Stevenson<br /><br />http://www.poemhunter.com/poem/ad-se-ipsum/
