If you're entrenched in something that isn't your lifelong passion--see below--you've got to get off those rails and find some way to get back on the right track.
I’ll take a good résumé or CV over a perfect one any day of the week because the good one can be done in a short time, allowing plenty of time for networking -- indisputably the single most important step in a job search -- whereas writing the perfect document could take you (and your CV or résumé) out of circulation for months.
Although it is true that some people use an early MBA as a launching pad, many others claim that the degree, without work experience behind it, only makes the job search more difficult.
