At the end of the day, it doesn't matter who's stronger, smarter, prettier or richer. The only thing that matters is whether you're happy or not.
“Our capacity to draw happiness from aesthetic objects or material goods in fact seems critically dependent on our first satisfying a more important range of emotional or psychological needs, among them the need for understanding, for love, expression and respect.”– Alain De Botton
“The true secret of happiness lies in the taking a genuine interest in all the details of daily life.”– William Morris
“Happiness consists more in conveniences of pleasure that occur everyday than in great pieces of good fortune that happen but seldom.”– Benjamin Franklin
“To enjoy good health, to bring true happiness to one’s family, to bring peace to all, one must first discipline and control one’s own mind. If a man can control his mind he can find the way to Enlightenment, and all wisdom and virtue will naturally come to him.”– Buddha
“Even a happy life cannot be without a measure of darkness, and the word happy would lose its meaning if it were not balanced by sadness. It is far better to take things as they come along with patience and equanimity.”– Carl Jung
