So you went through three years of law school only to eventually decide that you don't want to practice law? No problem. Your J.D. offers you a plethora of other opportunities that don't involve typical attorney work.
Good grades in Ivy-League law schools no longer guarantee recent law school graduates a good job. Post-recession, the market has made it very tough for law school students to land full-time, permanent jobs with law firms. So, instead of getting frustrated with the circumstances beyond your control and looking for other less preferred career lines, it is best to reset your focus. You can still hope for a great career path in law by using different means. Look up for positions for quasi legal jobs.
