Holy souls in Purgatory, is there anything you regret when you think of your life on earth?:You can read the rest at Ed's blog.
I deeply regret wasted time.... I did not consider it so precious, so fleeting, so irretrievable. For this reason my life is worth only half of what it might have been. Oh, had I but realized it then! Would that I could return to earth, how differently I would use the time given to me! Precious time! . . .
