My 27-yr-old daughter: β€œDad, when I was young, I remember you telling me something I’ll never forget. You said, when a team turns the puck over at the offensive blue line, it almost always ends up with a shot on their own net.” #parenting
Life hack: Put a ten of clubs in your wallet. When a cashier asks if you have a store card, pull it out and say, β€œIs THIS your card?” #hilarity

For years, I've used @Seesaw w great success as a way for my HS Ss to submit hwk daily. But, with their update, you can't import directly from a PDF maker like CamScanner anymore. So I need a new way for students to easily submit hwk digitally. Suggestions? #MTBoS #iteachmath

I remember breaking down to my Ph.D. advisor about how stupid I felt while troubleshooting a problem in my project when she handed me this paper. Years later it is still relevant to young students starting off in Science. It's ok to feel stupid, we all do on a regular basis.
