As much as we thirst for approval we dread condemnation.

To be totally without stress is to be dead.

Stress, in addition to being itself, was also the cause of itself, and the result of itself.

Mental tensions, frustrations, insecurity, aimlessness are among the most damaging stressors, and psychosomatic studies have shown how often they cause migraine headache, peptic ulcers, heart attacks, hypertension, mental disease, suicide, or just hopeless unhappiness.

The element of chance in basic research is overrated. Chance is a lady who smiles only upon those few who know how to make her smile.

Indeed, not all attacks-especially the bitter and ridiculing kind leveled at Darwin-are offered in good faith, but for practical purposes it is good policy to assume that they are.

Stress is not necessarily something bad it all depends on how you take it. The stress of exhilarating, creative successful work is beneficial, while that of failure, humiliation or infection is detrimental.
