There never has been a moment in all your life when sense-impressions were not pouring in upon you from every side, tending to disturb and annoy you and interfere with your concentration and progress. You can change the setting of your mental stage from portentous gloom to sun-lit assurance. You can concentrate your thought upon the useful, the helpful and the cheerful, ignore the useless and annoying, and make your life a life of hope and joy, of promise and fulfillment.
