The Ten Commandments (no not those you are thinking of .......
..... but those written by Angelo Roncalli, later Pope John XXIII)
Unfortunately I couldn't find a link to them in English but I think he must have had procrastinators in mind when he wrote his Eighth Commandment:
<<Only for today I will make an exact programme. Perhaps I will not fully adhere to it, but I will make it. And I will safeguard myself from two evils: hectic and indecisive actions.>>
I think this old man was remarkably modern in his outlook.
