“Man can learn everything if he will but try.”
“Try everything that can be done.... Learn your own possibilities.”
“Learn everything you can - everything. And then use all that you have learned to grow up too be a wise and good man.”
“The more a man looks at a thing, the less he can see it, and the more a man learns a thing, the less he knows it.”
“No man knows what he can do until he tries.”
“What man can be a real man...if he does not try and help make the world a better place!”
