Weaken a bad habit by avoiding everything that occasioned it or stimulated it, without concentrating upon it in your zeal to avoid it. Then divert your mind to some good habit and steadily cultivate it until it becomes a dependable part of you.
Paramahansa YoganandaNo matter what you are doing, keep the undercurrent of happiness. Learn to be secretly happy within your heart in spite of all circumstances.
Paramahansa YoganandaConsider whether fulfillment of the goal you have chosen will constitute success. What is success? If you possess health and wealth, but have trouble with everybody (including yourself), yours is not a successful life. Existence becomes futile if you cannot find happiness. When wealth is lost, you have lost a little; when health is lost, you have lost something of more consequence; but when peace of mind is lost, you have lost the highest treasure.
