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.

Many argue that Christianity is "different" from other religions - that it is primarily about love of one's fellow man. The Crusades, The Inquisition, Calvin's Geneva all prove that this is not the case. These events were pre-eminently about obedience to authority.

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

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 less you think counterfactually, the less you experience stress. Stress, in this light, isn't a bad thing. It's simply a warning system telling you that your mind has lost touch with what's real.

Even in this secular country, the threat posed by religious fundamentalists is never very far away. Every major religious text exhorts the same principles - that of unyielding obedience to a supernatural being, and renunciation of the intellect and personal aspirations.
