If you’re tired, do it tired.
Yesterday has no “o” in it. Today has one “o” in it. Tomorrow has many “o”s in it.
If “o” stands for “opportunity”, then yesterday has no opportunity in it. So, never do yesterday’s things today, because you won’t be creating an opportunity for yourself or anyone.
Do today’s things today, or tomorrow’s things today. Always be a step ahead of everyone else: that’s how you create opportunities.
