"If your success is not on your own terms, if it looks good to the world but does not feel good in your heart, it is not success at all."

"Try not to become a man of success but rather to become a man of value."

"Always bear in mind that your own resolution to succeed is more important than any one thing."

"Whenever I hear, 'It can't be done,' I know I'm close to success."

"We succeed only as we identify in life, or in war, or in anything else, a single overriding objective, and make all other considerations bend to that one objective."

"Each success only buys an admission ticket to a more difficult problem."

"I can't give you a sure-fire formula for success, but I can give you a formula for failure: try to please everybody all the time."

"The man of virtue makes the difficulty to be overcome his first business, and success only a subsequent consideration."

"Success is the ability to go from one failure to another with no loss of enthusiasm."

"Aim for success, not perfection. Never give up your right to be wrong, because then you will lose the ability to learn new things and move forward with your life."
