“The present is not exempt from the mistakes of the past.”
“Respect the past in the full measure of its deserts, but do not make the mistake of confusing it with the present nor seek in it the ideals of the future.”
“If you want the present to be different from the past, study the past.”
“You must learn from your past mistakes, but not lean on your past successes.”
“Time goes from present to past.”
“Nothing ever happened in the past that can prevent you from being present now, and if the past cant prevent you from being present now, what power does it have?”
