The first key is to understand what went wrong at your last job. Be as honest with yourself as possible. Was it the job, or was it you? Whether you left of your own accord or not, think about why you had to leave without a back-up plan in place, and what you can do to prevent such a situation in the future. This will help you clarify what you want most now, and how to get there and stay put. It will also help you understand your self better-from your unchallenged strengths to your unfortunate habits. Take a little time for stock-taking, soul-searching, and self-improvement.
