Wanna Be Happy

There are so many things in life that I really, truly, in my heart-of-hearts want.  But the one thing that stands high above the rest is the desire to be happy.  Not for a few hours or for a few days, but for a lifetime.  I know that rainy days are going to come.  I appreciate the rain, for without it, the flowers cannot grow.  But I don't want a life filled with torential rains.  I want to know that when they lay me in the ground, I had more happiness than I knew what to do with - my happiness was infectious.  Dear God, how do I get to that place?  How do I obtain infectious happiness?  I'm asking because I truly want to know the answer.  Can you help me find the way?
