What seriously heightens the quality of your life and comes for free or next to nothing?

When I had to cut down on work I rediscovered the joys of sleeping in a bit and especially of a slow breakfast. This really boosts my day and my morale.

Have some extra hot drinks, throw in an extra egg, some healthy desert, read the newspaper and listen to the radio, spend some quality time outside with the dog right after breakfast. Absolutely love it. During the week I get to do this on Tuesdays and Wednesdays. I make it a rule not to plan any activities with anybody else during those mornings.

Anything that has seriously added to the quality of your life that comes for free?
