Claude Adhémar André Theuriet: "There is no such thing as a happy life - there are only happy days."

You make your own happiness, you only get from life what you are willing to give. Look around you and see what you already have, if your not happy then only you can change this.

To love and be loved is the greatest happiness of existence.

Happiness is something spontaneous. Don't urge yourself to feel happy. Let the sun shine and take life easy. In my opinion that's the solution ;)

To me, the key to happiness is to accept your environment and appreciate it for what it is, rather than try to change everything. For instance, don't complain when you must wake up in the morning, but smile and enjoy the cool morning air. When I accept that I can't change and do everything and I'm only a small part of what I live in, I find it much easier to appreciate and enjoy life.
