Do not look back
no one knows how the world ever began
do not fear the future
nothing lasts forever
if you dwell on the past
or the future
you will miss
the moment.
rumi.
Did ruminate come from his name?
I prefer: 'life can only be understood backwards but must be lived forwards'...kirkegaard (I think).
He does not learn from the past is doomed to repeat it, he who does not look to the future with not be prepared for it, and he who lives only for today will likely as not never see tomorrow.
I think we’ve pretty much figured out how it all started.
