If you wait for perfection, you might wait too long.
There are some similar quotes, but so far as I know, this quote is mine. As the father, I kind of like it. But most parents love their own children. (If I am not the father, tell me now.)
This applies to all of life. And to Scrum and Agile and Lean. As the guy said to Jack Lemmon in that famous movie, "Nobody's perfect." In fact, not a single thing is perfect. So, my advice is: Don't wait for perfection.
Still a big problem out there. Too many people doing it. I usually don't do it more than 3 times per day.
Use this quote to work on 'em. Make life better now, before it gets to 'perfect.'
One of the biggest business problems we have.
