“Other people's views and troubles can be contagious. Don't sabotage yourself by unwittingly adopting negative, unproductive attitudes through your associations with others.”
“A healthy attitude is contagious but don't wait to catch it from others. Be a carrier.”
“Never be limited by other people's limited imaginations. If you adopt their attitudes, then the possibility won't exist because you'll have already shut it out...You can hear other people's wisdom, but you've got to re-evaluate the world for yourself.”
“It is your attitude about yourself that a man will adopt.”
“You walk around with a negative attitude and you're just naturally going to bring trouble and hard times down on yourself.”
“The trouble is if you don’t spend your life yourself, other people spend it for you.”
