How about a lovely walk on a beach?
One of the "Eight splendid truths of happiness" at "The Happiness Project" blog is
"One of the best ways to make yourself happy is to make other people happy;
So, with the altruistic intent of making you happier,
I went for a walk on a beach, painted pictures and made patterns, each of which invariably makes me happy.
Painted the rocks (oil pastels and Procion dyes).
Painted the sandy beach (watercolours, pens and a photo-edit shake).
Made a collage (watercolours, pens, magazine pages and a photo-edit shake).
And painted a nice little shape which was attached to a Funiculina quadrangularis (Collins Pocket guide to the Sea Shore) (oil pastels and Procion dyes).
I liked the colours in the collage and changed the rest of the colours to match, to make this.
Hope you're feeling happier now!
