Go for a walk. Alone. With someone. Or with a companionable dog. Even in rain and fog and cold temperatures.
Read the news less. Look at beautiful things more. Art. 500px photos. Instagram. Anything. Even street signs.
Do something I love. Experiment.
Speak to strangers.
Speak to known folks. Give compliments. "What a beautiful Short-haired Pointer!"
Share what matters.
