What makes you happy? What fills your soul? What makes you feel deeply satisfied even the next day?
Not what you should be doing. Not something that involves heroic amounts of will power. What do you enjoy?
For me, I enjoy painting and drawing. Reading weird, creative little books. And rambling through the woods in all weather.
I don't always do these things. In 2016, I will. Because they make me happy and feel fulfilled. What's your list?
