9. Not being realistic

Sometimes we expect our next job to make up for all the shortcomings of our previous positions: salary, benefits, vacation time, management support, career opportunities... but be realistic – no new opportunity can undo all the wrongs that you may have experienced in your career.

Be realistic about the company, the job, and what will make you happy. Concentrate on the factors that are most important to you and that are under your control. And, don't make demands that may make you appear unreasonable.
