When the going gets tough, we're not imagining it. Life's challenges are very real. And what we do with such challenges speaks volumes about our own level of personal happiness.
Justifying your every move and decision in an effort to be seen as right (all while proving others wrong) takes a great deal of time and energy. But once the ego is silenced and you allow a little humility in, you will have lightened your load and be on your way to a happier, more meaningful life.
