If Past = Present then Future Tense?

Build a future on a past?
How long do you think will that last?

How can, one build a future on a past?

Yours or someone else's how does it matter
One comes first and follows then the latter

Life a string of moments lived each moment
Don't let past be it's degrading rodent

Present, let that be a gift

Wrapped in beautiful colours, a pretty ribbon
Be prepared to face, when you pull that open,

The chasms, the skies, depths and heights
Love and hate, and glory and spite

Take it all in your stride

Woman! Remember, if Past = Present
Your Future will always be Tense!

Just learn lessons from the past

Treat it as a Gift, a Present and
Build your future to make it last!
