Window To The Past
Past holds the pillars of today.
We often look back in time on things and use past events to predict the future.
That's great because Historia est magistra vitae - (History is the teacher of life) and we should use that knowledge not to repeat the same mistakes twice.
However, be careful not to get too caught up in the past, you still live in the present, and things change. People change. You're not the same as you were yesterday. You evolved.
Try taking that into account when learning from the past, but still... learn.
