Just because you weren't successful at one job, doesn't mean you won't be successful at your next job. Taking a position just to pay the bills is understandable and most times - necessary, but continue to search and apply for the job that fits you best. What is your passion? Music, sports, home décor... find work that incorporates your passion. When you love what you do... jobs become careers. Take the time to find out what you're really good at...what your passion is...then align, engage and achieve!
