Inadequate
We refer to something as inadequate when it is not able to suffice the need which it is suppose to meet. It can be because of the limitation of the thing, the drawbacks or the incapability. Considering human perspective, inadequacy is a term which should ideally not be used for any human being. However, while considering a specific situation or job role, the framework or the set up might consider a person less appropriate due to the lack of certain skill which is quite important for the job role. In such cases the person might lack the adequate skills. The feeling of inadequacy develop from the negative situational and environmental feedback that a person receives because of his or her activities. These feelings if not addressed appropriately might lead towards a feeling of helplessness or hopelessness, reduced self confidence and lack of well being, resulting in mental distress.
