To rebuild confidence when job hunting, focus on writing down past successes, setting goals, creating a networking group, practicing self-care, and volunteering. 

Losing a job can be a huge blow to one’s confidence, especially when job hunting takes longer than expected. To rebuild confidence, there are five strategies to consider. Firstly, write down and read 10 reasons why you have been successful in the past to counter negative self-talk. Secondly, set daily and weekly goals to achieve both in the job search and other areas of life, such as home projects. Thirdly, create a networking group with others in your field or desired career pivot to share ideas and provide job leads. Fourthly, practice self-care and do things you enjoy with achievable goals attached. Lastly, volunteering can provide opportunities to upskill and help others while boosting confidence. By focusing on building up confidence holistically, job seekers can approach their next opportunity with more self-assurance.
