An effective antidote to the stress of modern life is to hang out with a baby. Seriously.
Babies live completely in the moment. Give them a toy and they are completely absorbed in it. Show them another, and that becomes their new focus, the old one forgotten. They wouldn't know multi-tasking if it bit them in the butt.
Tiny zen masters- babies. They know the wisdom of "When sitting, sit. When standing, stand. Above all, don't wobble."
Well, at least until they try to walk.
