Happiness is not an accident. Nor is it something you wish for. Happiness is something you design.
Whatever the situation, you are the only one who determines your happiness. Sure, others may contribute to your being miserable. But you are the only one who settles into happiness or misery.
Happiness is shaped and molded from your well-being. Moreover, happiness is a feeling. Aha! We have the choice to decided whether we will feel happy or sad.
