Human beings are divided into mind and body. The mind embraces all the nobler aspirations, like poetry and philosophy, but the body has all the fun.

True peace of mind comes from accepting the worst. Psychologically, I think, it means a release of energy.

Worry is most apt to ride you ragged not when you are in action, but when the day's work is done. Your imagination can run riot then and bring up all sorts of ridiculous possibilities and magnify each little blunder. At such a time," he continues, "your mind is like a motor operating without its load. It races and threatens to burn out its bearings or even to tear itself to bits. The remedy for worry is to get completely occupied doing something constructive. Said by James L. Mursell

When we are not busy, our minds tend to become a near-vacuum. [...] Nature also rushes in to fill the vacant mind. With what? Usually with emotions. Why? Because emotions of worry, fear, hate, jealousy, and envy are driven by primeval vigour and the dynamic energy of the jungle. Such emotions are so violent that they tend to drive out of our minds all peaceful, nappy thoughts and emotions.
