Exceptionally hard decisions can deplete your energy to the point at which you finally cave in. If you mentally crumble and degenerate into negative thinking, you'll magnify the problem to the point where it can haunt you.

An idea is worthless unless you use it.

If you believe in others and give them a positive reputation to uphold, you can help them to become better than they think they are.

If you think you are beaten, you are. If you think you dare not, you don't. If you'd like to win but think you can't it's almost certain you won't. Life's battles don't always go to the stronger or faster man, but sooner or later, the man who wins is the man who thinks he can. A happy person is not a person with a certain set of circumstances, but rather a person with a certain set of attitudes. I may not be able to change the world I see around me, but I can change the way I see the world within me.

Relational skills are the most important abilities in leadership.

A visionary company is like a great work of art. Think of Michelangelo's scenes from Genesis on the ceiling of the Sistine Chapel or his statue of David. Think of a great and enduring novel like Huckleberry Finn or Crime and Punishment. Think of Beethoven's Ninth Symphony or Shakespeare's Henry V. Think of a beautifully designed building, like the masterpieces of Frank Lloyd Wright or Ludwig Mies van der Rohe. You can't point to any one single item that makes the whole thing work; it's the entire work-all the pieces working together to create an overall effect-that leads to enduring greatness.

Every sailor knows that you can't sail a ship that isn't moving forward, strong leaders understand that to change direction, you first have to create forward progress.
