Learn to be the source of your happiness..
Unfortunately, we measure our successes by the Goals we lose and not the goals we make. That is a sad measurement of success.
We love to measure success by counting all that we do not have. Of course, we conveniently forget to count our blessings. Thus even after winning, we believe we are losers and feel unhappy.
The promotions, rewards and raises we got until now, are quickly forgotten the very moment we do not get that last promotion. We quickly forget how many were unhappy and sad when we superceded the others when we had won. The pain we recall is the one we get only when we are superceded by the others.
We are the source of our own unhappiness. Only we can be the source of our own happiness.
