The more you worry, the more you throw off the delicate balance of hormones required for health.

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.

Throughout history, independent minds have carried mankind forward. Whether they identified how to make fire or manufacture tools, develop rational philosophy or create man-glorifying art, pioneer scientific knowledge or invent the electric light, independent thinkers have created the goods on which human life and prosperity depend.

The elusive truth is that there is nothing stress-producing in the physical world. Things simply are. Molecules move. Light and sound appear.

The more you worry, the more you throw off the delicate balance of hormones required for health.

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.

You can't tell yourself that your stress is produced in your head and feel better. You still need to learn how to create a change.
