Do not get addicted to the highs, for they are followed by the lows.  This is one of the rules, that Life in your world seeks balance.  Oh, the highs feel so good.  Joy!  Exuberance!  Love!  There is nothing wrong with these, but you will then go to great lengths to maintain the extremes of these experiences.  How to find the happy medium?  Gratitude, dear friend.  When you are feeling manic, be aware.  The opposite of mania is depression.  Catch the extremes in your awareness and transmute them to gratitude for what they have to teach you.  Return to the center resting on gratitude and breathe in the peace.  A recipe for balance.
