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

Stress is not the spice of life any more than arsenic is. And without it, you won't feel bored.

The number of stressors has multiplied exponentially: traffic, money, success, work/life balance, the economy, the environment, parenting, family conflict, relationships, disease. As the nature of human life has become far more complicated, our ancient stress response hasn't been able to keep up.

The truth is that stress doesn't come from your boss, your kids, your spouse, traffic jams, health challenges, or other circumstances. It comes from your thoughts about these circumstances.

The reason humans experience so much more stress than other species isn't just because we think more, but also because we think differently.

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