If you live in the past
sadness will reappear.
If you forget the past
You can't learn from it.

So, don't live the past,
but don't forget the past.

Let it be your guidance
to be someone better
and to make better decisions
for the life you live.

The past is something you shouldn't forget
because whatever it is that you choose to forget
just be glad that it'd happened then not now.
Because right now is the present.
And now you have  the knowledge to be someone better
and to make better choices for the future that lies ahead of you.

Don't live in the past,
but don't forget the past.
Continue to learn from it
to build a better future.
