Happiness

If we are not happy, if we are not peaceful, we cannot share peace and happiness with others, even those we love, and those who live under the same roof. If we are peaceful, if we are happy, we can smile and blossom like a flower, and everyone in our family, our entire society, will benefit from our peace. - Thich Nhat Hanh

True happiness is to enjoy the present, without anxious dependence upon the future, not to amuse ourselves with either hopes or fears but to rest satisfied with what we have, which is sufficient, for he that is so wants nothing. The greatest blessings of mankind are within us and within our reach. A wise man is content with his lot, whatever it may be, without wishing for what he has not. - Seneca

We are at our very best, and we are happiest, when we are fully engaged in work we enjoy on the journey toward the goal we’ve established for ourselves. It gives meaning to our time off and comfort to our sleep. It makes everything else in life so wonderful, so worthwhile. - Earl Nightingale

Pain and illness, the deaths of that one love, and discomforts and disappointments mar the happy norm, but they do not alter the fact that happiness is the norm, nor affect the tendency of the continuum to restore it, to heal it, after any disturbance. - Jean Liedloff

Happiness is a choice, not a result. Nothing will make you happy until you choose to be happy. No person will make you happy unless you decide to be happy. Your happiness will not come to you. It can only come from you. - Ralph Marston
