People often want to hold onto the past. What most of them don't realize is that holding onto the past can't hurt you and can also hurt those around you.
Remembering the past is one thing. Looking back at good times is not a bad thing, but don't live your life there.
Remembering bad things that happened can sometimes help you keep from making the same mistake in the future, but don't live there.
We have friends who come and go. Sometimes we try to hang onto people that are no longer relevant in our lives. When I say they're no longer relevant I mean that sometimes these people hurt us or hinder us, but we're so used to having them there that we cling to what we know instead of doing what's best for us and for those around us.
We can also hold onto past hurts. We hold onto what people have done to us, we hold on to past failures, we hold onto things that, yes, they happened, yes, it stinks, but that can push us away from a good future and that can push good people away from us.
Each and every one of us have a story that is all our own. What we do with that story is up to us. We can let it make us better or bitter. It's your choice. I hope you choose well.
