We all want to be happy. But we sometimes think of happiness as a thing that happens to us — something we have no control over. It's easy to link the idea of happiness with the situation we're in. We might tell ourselves, "If only things were different, then I'd be happy."
Happiness, sorrow, victory, defeat, day-night are the two sides of the me coin. Similarly life is full of moments of joy, pleasure, success and comfort punctuated by misery, defeat, failures and problems. There is no human being on Earth, strong, powerful, wise or rich, who has not experienced, struggle, suffering or failure.
