“Winners never quit and quitters never win” (Vince Lombardi 1913 - 1970)
“ I quit school in the sixth grade because of pneumonia. Not because I had it but because I couldn’t spell it." (Rocky Graziano 1919-1990)
"I'm more proud of quitting smoking than of anything else I've done in my life, including winning an Oscar." (Christine Lahti 1950 - )
The more I thought about the topic of “quitting” the more I realized that there are many different ways of looking at it than the simple assumption that a quitter is a loser. Hence the two quotes above.
