I don't trust happiness. Even a bear of little brain knows that it is fleeting. It is not a permanent state of being, and one mustn't cling to it. I'm not sure it is even something one should strive for. It is definitely not something sold to you.
Happiness is waking each day and rejoicing in the sunshine or the rain, the spiders in your garden, the coffee in your cup, the feet that carry you to your destination, the smiles of your friends and even those of strangers. It is being able to laugh at yourself and the ridiculous path you've chosen.
