The first requisite for success is the ability to apply your physical and mental energies to one problem incessantly without growing weary.

The key to success is to keep growing in all areas of life - mental, emotional, spiritual, as well as physical.

Memory is the friend of wit, but the treacherous ally of invention; there are many books that owe their success to two things; good memory of those who write them, and the bad memory of those who read them

Success is what you do with your ability. It's how you use your talent.

When we fail, our pride supports us, and when we succeed it betrays us.

Experience shows that success is due less to ability than to zeal. The winner is he who gives himself to his work, body and soul.
