There are subtle forms of evil which you should guard yourself against as you would against disease and pestilence. When you feel toward others the first intimation of resentment, envy, contempt, or discontent, annihilate the thought on the instant. Drive it out of your mental world and be done with it. As a great growing personality you should be eager to discover and destroy any weakness in yourself.
Let thoughts of appreciation, admiration, approval, gratitude, and generosity be uppermost in your mind. The best antidote for evil of any kind is to keep your mind filled with good thoughts and your life occupied with good works. As you ascend in your thought, you will find yourself in a new world of beauty and usefulness.
