Did you read a book titled "The power of Now" by Eckhart Tolle? I love this book.There is a story given in prologue of this book. It tells a story about a beggar begging on the street. A stranger comes to him and asks him about the box on which the beggar is sitting. He asks the beggar whether he has opened the box or not. The beggar says "No" and the stranger asks to open it. To his amazement, the beggar finds gold and silver coins in the box. The stranger says, you are sitting on the box of gold coins and you are begging for coins from other. This is the same case with happiness.
We look for happiness outside when it can be found within us. By living in the present, we can find happiness. If we remember the past, it brings guilt and regret and if we think about the future, it brings fear and anxiety. If we live in the present, there is no regret, guilt, fear and anxiety. So, live fully in the present. Be alive and don't let your music within die. Play, have fun and at the same time do your work or study. This is life.
To your happiness!
