Happiness is a state of mind, not a destination. It is not necessary to find love before finding happiness.
Happiness arises from the way you think about events: interpreting them positively; finding what is good or instructive; extending to others the benefit of the doubt; overlooking what is unimportant; putting adversity behind you; setting goals that are inspiring as well as stimulating; cultivating your creativity; ENGAGING IN LIFE.
I believe that, but only to a certain point. If you suffer from depression, no amount of happy thoughts is going to fix anything.
