Thomas a Kempis

If we would put some slight stress on ourselves at the beginning, then afterwards we should be able to do all things with ease and joy. It is a hard thing to break through a habit, and a yet harder thing to go contrary to our own will. Yet, if thou overcome not slight and easy obstacles, how wilt thou overcome greater ones? Withstand thy will at the beginning, and unlearn an evil habit, lest it lead thee little by little into worse difficulties. Oh, if thou knewest what peace to thyself thy holy life should bring,…and what joy to others, methinketh thou wouldst be more zealous for spiritual profit.
