living in the past is synonymous with driving backward rather than forward. And you should agree with me that whoever that drives a car backward cannot make headway. I mean, he or she will hardly reach his or her destination. May I tell you, that's just an aftermath of living in the past. Yes! you heard me right, you will hardly realize your dreams, visions or aspirations if you keep on living in your past. Thus, desist from focusing on all that is behind you i.e. your past mistakes, setbacks, failures, misfortunes and things like that. Anyway, the ball is in your court as ever. So, feel free to play it as you wish.
