Lazarus (1966) offers this definition of stress: "stress occurs when an individual perceives that the demands of an external situation are beyond his or her perceived ability to cope with them". This definition is arguably now old-fashioned, but we have included it here as we want to draw two things to your attention, and think this quote can be useful in illustrating them.
Firstly, this quotation highlights that stress can be about perception, and reinforces what we have already talked about in terms of stress being personal and different for everyone. One person might see a large pile of work on their desk and not worry about it, perhaps even be motivated by it. Someone else might look at the same workload, turn pale as a ghost and worry about how they are going to cope with it. Which brings us on to the next point, which is outlined on the following page.
Stress is a medical condition and it can have a serious effect on your health. If you think you are suffering from stress it is crucial that you consult a medical professional.
