Make little things bother you. Don't just let them, MAKE them.

Lose your perspective on things and keep it lost: don't put first things first.

Get yourself a good worry, one about which you cannot do anything.

Be a perfectionist, which means not that you work hard to do your best, but that you condemn yourself and others for not achieving perfection.

Be right. Be always right. Be the only one who is always right, and be rigid in your rightness.

Don't trust or believe people, or accept them at anything but their worst and weakest.

Be suspicious. Insist that others always have hidden motives.

Always compare yourself unfavorably to others.
This guarantees instant misery.

Take personally everything that happens to you.

Don't give yourself whole-heartily to anyone or anything.
