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

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

Negative thoughts stick around because we believe them, not because we want them or choose them.

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.

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.

Altruism demands that an individual serve others, but doesn’t stipulate whether those others should be one’s family, or the homeless, or society as a whole. Collectivism states that, in politics, society comes first and the individual must obey. Collectivism is the application of the altruist ethics to politics.
