You know the awesome feeling of a clear, fresh headspace that lets you do deep thinking, to find interesting solutions to tricky problems or to get in the zone and find flow. You also know the agitation you feel from mental chatter or the slog that comes from having to produce work when you are mentally tired.
The good news is you can learn to recognize more quickly the state of your headspace and to employ tools and techniques to that help you re-establish clarity and mental bandwidth. Let go of (p)re-hashing conversations and events and retrain your inner mental dialog.
Having a clear headspace is about more than mind over, well, mind. Perhaps surprisingly, one of the keys to returning to your clear headspace is recognizing what is going on with your body.
