That's a great quote from Calvin Coolidge Cristina. You are right. Persistence is one of the keys to success. It's certainly been true in my case. It's taken sheer willpower to keep going and persist in spite of challenges and failures. I'm writing a chapter on persistence for my next book. So, this is especially topical for me. Thanks!
