Mutter the Right Way
You might look and sound crazy (especially sans earbuds), but who cares? Talking to oneself (aloud or not) is now a scientifically proven brain-booster, finds a review of 32 self-talk intervention studies from the University of Thessaly in Greece. It helps you to pay attention, steadies you emotionally and cues you to act.

Try this: Self-talk is most effective when learning something new or enhancing performance. Little instructions (Do this. OK. Now, do that) are more helpful than "atta-girl" self-cheering, the researchers found. In one study, athletes ran faster when they spoke cue words to themselves (push, heel) through a race.
