So one year into my first full-time job, I was flourishing in the position (corporate setting) but had concluded that, long-term, this field was not for me. So I left my job without having another lined up and planned on volunteering for a non-profit campaign but quickly realized that I had made a mistake. This position was not nearly as challenging and enriching as my old job. I realized that, even if the other job did not comport with my long-term interests, I still had much to gain and much to offer from returning there. So I left the volunteer position and spent about two months traveling. During this time, I also approached my former employer, who welcomed me back and in fact offered me a substantial promotion. In sum, I returned to my old place of employment after a three-month absence. I have since been there two years and am now applying for admissions. How in the world can I explain this to an adcom?
