Looking backward most time means an inability to let go of past relationships, past mistakes, past choices, or even past health. We all have something in the past that is hard for us to let go of. Looking backward is often full of regret and/or sadness.
Looking forward, on the other hand, means putting the past behind you and focusing on what’s ahead. It means having hope that what’s ahead of you is better than what’s behind you. It means giving your attention to your future, not your past.
