Every event has a purpose and every setback its lesson. I have realized that failure, whether of the personal, professional or even spiritual kind, is essential to personal expansion. It brings inner growth and a whole host of psychic rewards. Never regret your past. Rather, embrace it as the teacher that it is.
If we believe in nothing, if nothing has any meaning and if we can affirm no values whatsoever, then everything is possible and nothing has any importance.
