Your career is too important to spend your time looking for a job on a variety of sites. If you were sick you would find the best possible doctor. You should do the same thing with your job site. There is no better job board in the world for legal professionals: LawCrossing shows you jobs from every single employer career page, job website, association website
One way to stay positive: Make copies of all the nice things people have written about you- customer letters, performance appraisals, awards. Tape them to your mirror. Read them every morning and night and remember how good you really are.
