“Today was good. Today was fun. Tomorrow is another one.”
Variant: The good times of today are the sad thoughts of tomorrow.
“Today was good. Today was fun. Tomorrow is another one.”
Connections (1979), 1 - The Trigger Effect
Context: The Egyptians built an empire and ran it with a handful of technology... the wheel, irrigation canals, the loom, the calendar, pen & ink, some cutting tools, some simple metallurgy, and the plough, the invention that triggered it all off. And yet look how complex and sophisticated their civilisation was. And how soon it happened, after that first man-made harvest. The Egyptian plough and those of the few other civilisations sprang up around the world at the same time... Gave us control over nature... And at the same time, tied us for good, to the things that we invent so that tomorrow will be better than today. The Egyptians knew that. That's why they had gods. To make sure that their systems didn't fail.
“The good you do today will be forgotten tomorrow. Do good anyway!”
Trauma
Lyrics, Loveppears
A Conversation with Ward Cunningham (2003), To Plan or Not To Plan
Context: To worry about tomorrow is to detract from your work today. Time you spend thinking about tomorrow is time you're not spending thinking about what to do today. The place you leave in the code because you think you'll need it tomorrow, is actually a waste of time today — and a liability tomorrow. It does more harm than good.
