What Are Your Favorite "Sayings" - Wisdom, Humor, One-liners, etc

Mates,

I think we all have some favorite capsules of wisdom and/or humor that we have learned over the years.  Some are pretty ubiquitous like, 'A rolling stone gathers no moss' or 'A fool and his money are soon parted'.   Some are pretty funny, particularly when delivered at the right time - maybe something like your dad told you as he chased you around the house: "I brought you into this world and I can take you out!" 

I can think of a couple that I have frequently said or at least thought.  One comes from one of my favorite investigators back in the day, an ex-marine Sgt, black belt, war vet, and all around genuinely tough dude.  He opined: "The street is a hard school, but a fool will learn in no other".  Another one that I have taught my kids and literally every team that I've ever coached, "Like vinegar to the teeth and smoke to the eyes, so is the sluggard to those who sent him" - i.e., nobody likes the lazy teammate, get out there and hustle! 

So today's question is pretty simple:  Share your favorite 'sayings', and maybe even the background about how you learned it, when you've used it, and things like that. 

Some positive news about our serious C-19 situation seems to come out every day.  Keep the faith and Go Blue!
