“If you realize you aren't so wise today as you thought you were yesterday, you're wiser today.”
“When you come to see you are not as wise today as you thought you were yesterday, you are wiser today.”
“You should never be ashamed to admit you have been wrong. It only proves you are wiser today than yesterday”
“You are today the result of your thoughts of yesterday, and the many yesterdays preceeding it. You are forming today the mold for what you will be in the years to come.”
“Yesterday is a cancelled check; tomorrow is a promissory note; today is the only cash you have - so spend it wisely.”
“Strive to be better today than you were yesterday.”
