A brisk lesson on dealing with crises from Dr Maxwell Maltz, writing in his classic, Psycho-Cybernetics: 

"Successful people are able to rise above crises by relaxing no matter what the external situation.

Their believe in themselves, the strength of their self-image is impenetrable armour, which protects them against shattering events."

Interestingly, Dr Maltz added these astute observations:

"Stand up to crises. Don't let them throw you. Fight to stay calm... even surmount the crisis completely and turn it into an opportunity. Refuse to renounce your self-image. No matter what happens, you must keep your good opinion of yourself. No matter what happens, you must hold your past successes in your imagination, ready for showing in the motion picture screen of your mind. No matter what happens, no matter what you lose, no matter what failures you must endure, you must keep faith in yourself. Then you can stand up to crises, with calm and courage, refusing to buckle then you will not fall through the floor. You will be able to support yourself."

“Close scrutiny will show that most 'crisis situations' are opportunities to either advance, or stay where you are.”
