I feel energized by every single breath I take.

About twenty thousand a day, and you'll consciously register maybe four of them. It's the most reliable thing your body does and the least remarked upon.

Sitting at a red light waiting for green is as good a place as any to catch one. Not a technique — just attention landing somewhere it doesn't usually go. Whether a single breath energizes you is arguable. What isn't arguable is that noticing one interrupts whatever loop your head had going. Some days that turns out to be the same thing.
