At the end of the day, we are all looking forward to one single thing: Happiness!
Most of the time, we believe that if we manage to fix the problems in our lives -if that day ever comes- happiness will knock on our doors eventually. We focus so much on the external events and effects, we forget that actual happiness lies within. The famous quote from psychoanalyst Carl Jung explains this situation beautifully:
"Who looks outside, dreams; who looks inside, awakens."
