Mr. Lincoln's Advice on Success

Lincoln said or wrote a lot of memorable things, and the one you cited is a dandy. Here are a few of my favorites:

"You cannot strengthen the weak by weakening the strong. You cannot help small men by tearing down big men. You cannot help the poor by destroying the rich. You cannot lift the wage earner by pulling down the wage-payer. You cannot keep out of trouble by spending more than your income. You cannot further the brotherhood of man by inciting class hatreds. You cannot build character and courage by taking away a man's initiative and independence. You cannot help men permanently by doing for them what they could and should do for themselves."
-Abraham Lincoln

"I suppose people are about as happy as they choose to be."
-Abraham Lincoln

"All my life I have tried to pluck a thistle and plant a flower wherever the flower would grow in thought and mind."
-Abraham Lincoln

"Be sure you put your feet in the right place, then stand firm."
-Abraham Lincoln

"Better to remain silent and be thought a fool than to speak out and remove all doubt."
-Abraham Lincoln

"Don't worry when you are not recognized, but strive to be worthy of recognition."
-Abraham Lincoln

"I am not bound to succeed, but I am bound to live by the light that I have. I must stand with anybody that stands right, and stand with him while he is right, and part with him when he goes wrong."
-Abraham Lincoln

This is my favorite Lincoln Quote.

"Things may come to those who wait...but only the things left by those who hustle."

My favorites are
"Important principles may, and must, be inflexible."
"In the end, it's not the years in your life that count. It's the life in your years."
"I walk slowly, but I never walk backward."
