What is self-esteem? When your self-esteem is low, you feel depressed and hopeless. You see life negatively. Everything seems difficult, or too much trouble. It feels as if the world is a bad place, full of people who will abuse or ignore you; you feel helpless to do anything about it. You see yourself as a victim. You treat other people as potential enemies, or saviours, and sooner or later they treat you badly or let you down. This further lowers your self-esteem, and so a vicious cycle is set up. When your self-esteem is good, on the other hand, the world feels like a good place, full of friends, potential pleasures and opportunities. You can assert yourself, ask for what you want and express your feelings. You feel potent, and know that you can make a difference. Other people in general respond to your positive attitude, so that, even when you don't get your way, you feel good about yourself and them. This reinforces your self-esteem and stimulates your inner growth.

The above two paragraphs describe the two ends of a spectrum. If they were shown as two points joined by a line, few of us would say that we live at either end of it. Most of us get through life somewhere near the positive end, and we move up and down it in response to things that happen to us. Events involving loss or threat, such as losing your job, ending a relationship, being bereaved, falling ill or having your house broken into, can give your self-esteem a huge knock. On the other hand, when you are promoted, fall in love, pass an exam, face a challenge or win a prize, then you feel pleased and proud – your self-esteem is boosted. A healthy person can absorb some knocks to their self-esteem and bounce back if their basic sense of self is positive.
