what drives a person to be anxious ?

Most time, its my work..with ontime deliveries and work loads. I try to divert mind on music and i feel better.

There are other factors that could lead to anxiety. when you have a be task before you to perform for high result. when writing exams. uncertain expectation.

lack of exposure and experience also may tend for a person to be more anxious.He has nothing to share and with that, self-confidence is greatly affected.

Non-medical related anxiety is a feeling of unrest arising from uncertainty about the outcome of an event or situation. It could be unhealthy when one feels uneasy that a bad thing might happen. It could also be healthy whereby one expects some good tidings, people or event. While apprehension matches the unhealthy form of anxiety, eagerness describes the healthy one. In most cases, it is the unhealthy type of anxiety that gives cause for concern because of its destructive impact on the health of the person concerned. Unhealthy anxiety could have to do with a lack of self-confidence such as when a boy attempts to approach a girl for friendship for the first time, or when a weak student is preparing for a vital exam, or one is going for the driver's licence test. However, not all unhealthy anxieties are due to a lack of self-confidence. One could feel anxiety for the rain if one is organizing an open-air party. Similarly, the fear of another volcanic eruption in a particular region or location at a particular period of time is another form of anxiety which has nothing to do with self-confidence. Such anxieties are due to factors outside human control. Whether a non-medical anxiety is due to a controllable or an uncontrollable factor, the bottom line is uncertainty, and the basis of the uncertainty is either well defined or deductible. In the case of medical anxiety, the causative factor may not be so obvious or clearly defined to the sufferer, or it may be apparent to the sufferer but not obvious to the people around him/her.
