" … to be free is to live in the present. If we are stuck in the past, saying, ‘If only I had gone there instead of here,’ or ‘If only I had married someone else,’ we are living in a prison of our own making. Likewise. if we spend our time in the future, saying, ‘I won’t be happy until I graduate,’ or ‘I won’t be happy until I find the right person.’ The only place where we can exercise our freedom of choice is in the present. "
