A happy person is a person that loves themselves. When you love yourself beyond all of your inadequacies, and see beyond your own imperfections, you can reach enlightenment.
If you agree with Joseph Conrad then “we live as we dream… alone.” I’d say this is the truest and most honest thing any human has ever said. That presents both a problem and a solution. We are alone, but in that loneliness we still have our-self. All too often in our lives we place too much of our own happiness in others, when the only person we need to place happiness in is ourselves.
