Sometimes my boss lets me take off my shock collar and run around outside.

Photoshop, Illustrator, InDesign, ink and watercolour, baking, how to murder house plants, hedgehog behavioural patterns, how to draw various breeds of dog.

Not eating crappy food all the time.

If it takes less than two minutes, do it now.

You will only really get four or five solid hours of work done in the average office day. Don't beat yourself up about it.
