Happiness at all times

I was waiting at the bus stop. From afar, I saw this young, pretty and fair girl with long hair, wearing a bright flowery turquoise dress, walking towards the bus stop. She was walking with an awkward limp, guided by her friend. Both were chatting happily. I notice she looked so cheerful, so radiant, full of smiles, laughter and happiness. 

This is a big difference compared to most of us, the normal able-bodied humans, who look so drab, solemn and miserable as we go about our daily chores, going to work or meetings, at the bus stop or in the train. If only we can exude such happiness and joy with life at all times. Value and cherish our life no matter how much discomfort and pain we feel.
