[Happiness] is not determined by our circumstances but by our responses to them. (Source unknown)
America’s first “First Lady,” Martha Washington put it this way, “The greater part of our happiness or misery depends upon our dispositions, and not upon our circumstances.” So, there we have two ideas about being happy. First, determine to respond positively to your circumstances, and work hard at developing an optimistic outlook on life.
For the despondent, every day brings trouble; for the happy heart, life is a continual feast. (Proverbs 15:15)
