In the last week, I've heard the same thing from two different people: There's no point in looking back. That's not where you want to go anyway.
My husband is more succinct. He just says: I don't look back.
That philosophy, I believe, is the only thing that keeps a person's head from going below the water, from falling into the abyss, from whatever precipice you find yourself teetering on.
Don't look back.
Looking back, whether it is at past successes or failures, does nothing to help your present reality. If you keep dwelling on what has gone wrong (my instinctive go to reaction, unfortunately) it will only cement your negative thinking. Conversely, if you only think about all the wonderful things that have happened in the past, it will either make you crave more and bigger things (which can be good sometimes) or make you dissatisfied with what you have now (it's not as good as it was before!). Either way, you won't be happy.
So what's the answer?
Move forward. Keep your eye on the next day.
Or better yet.
Deal with today. Enjoy today. Make it through today. Make today count.
Because while the past may hold some answers, it can also hold you back.
