Happiness requires both pleasure and purpose - neither alone is sufficient.

The highest manifestation of life consists in this: that a being governs its own actions.A thing which is always subject to the direction of another is somewhat of a dead thing.

信心不是乐观或悲观，也不是性格属性。它是对积极结果的期待。

Integrity is the foundation of lasting success.

领导力意味着为了更美好的明天而在今天做出艰难的决定。
