This reminds me of my high school history teacher, Mr. Sperling. At the time he seemed ancient but I doubt he was even 30. He used to tell me "discipline is the key to true creativity." Words I obviously have remembered. Decades and decades later, a classmate announced on FB that she'd discovered Mr. Sperling - I forget where. But I looked him up, there was an email...and I finally got to thank him. Bless him forever, plus he sweetly pretended to remember me! Thx, Tree!
