This belief in the notion that something external is critical to our happiness also serves to reinforce the patterns of our ego, which strengthens itself when we identify with the "little me" struggling in this constant pursuit against the big old world.
If we spent one-third of the energy that we spend on chasing happiness on getting better at being in pain, our experience of being alive would dramatically expand. We'd need to chase less and run away from less.
Over the past several years, I have been researching the relationship between happiness and success, only to discover that the problem is not that we forget to pursue happiness, but that we are pursuing it with the wrong formula.
The meaning you give to what happens to you totally determines your reaction to what happens to you. One meaning can lead to suffering; another meaning of the same event can lead to excitement and happiness.
