I am writing this as a reminder to myself.

Stop for a moment.  Put everything down.  Take a deep breath in ... and take just a moment.  Push all thoughts out of your head.  Put all of your attention on your breath and on this moment.  Completely empty your mind and be fully aware of the "NOW".  Everything in your life, all your troubles, stressors, challenges can wait for just one moment.  For just one moment be happy, be at peace.

Ok ... moment is over.  Do it again.  Repeat as necessary.
