I work with job seekers who are often "stuckees" as I refer to them. My definition of one is about someone who can't seem to move or take action on their own behalf. Any action!
For example, the first or second job interview rejection shuts them down. I think poor self-esteem is often one of the reasons for giving up.
Job seeking is often a game where new or returning job seekers don't know the new rules. One of the rules they don't know about is to take risks. The job seeker must often create their own rules and not worry about rejection.
Being rejected for a job, once or twice is bad enough, but what about several times of facing rejection? Rejection can often make anyone feel they are now useless.
I think one of the cures of being a "stuckee" is to have a group of people around that is accepting of the job seeker, no matter what. Supportive people can offer hope.
How to keep going on in the face of many rejections? Support is vital. Another idea is to understand that circumstances change; change for the better is on the horizon. However, it is the place where people provide hope and resources towards a fulfilling job search.
Risk, plus action, and support can help get the job hunter out of the most awful of stuck places!
