When a friend is sick, I see the situation for what it is, not what it isn't, and I offer to help as much as she wants, not as much as I want.

A hero has faced it all: he need not be undefeated, but he must be undaunted.

During the financial crisis, I worked with hundreds of executives who struggled as a result of their thoughts about job security. When their beliefs changed, so did their emotional experience - and they were then able to focus on the task at hand more effectively.

We need to distinguish between stress and stimulation. Having deadlines, setting goals, and pushing yourself to perform at capacity are stimulating. Stress is when you're anxious, upset, or frustrated, which dramatically reduce your ability to perform.

People around the world now complain about stressors everyday, and the word shows up throughout professional and lay literature. But in reality there is no such thing as a stressor. Why not? Because nothing has the inherent power to provoke stress.

Stress is never a given. There are people who get divorced amicably. There are people who pack up and move with no emotional toll. There is no stressor 'out there' in the world. We experience stress - or we don't - depending on what we believe.

If you're successful and stressed out, you're succeeding in spite of your stress, not because of it.
