Something that happened in the past can't be changed.
It's done you can't come back and modify it. The only thing you can change is how you look at it.
There's always a way to change how we see the past. We can't change the reality of it, but we can change how we look at it.
If you choose to change how you see your past, then you can change it. It’s all about you.
If you choose to cherish those moments, then they stay vivid in your mind. The more you bring back memories, the more vivid they remain in your brain. If you don’t bring them back, they’ll start to become blur and someday you’ll remember only some part of it.
Choose to remind yourself of the good moments. Bring back the good feeling of those moments. And you’ll bring it into your present. Happy memories brings the happy into the present.
