2) Plant Superintendent (3 years)

- Stuck in the same role for 3 years with very few opportunities to expand my horizons at work.

- Muay Thai Fighter. Won first amateur fight at Arnold Sports Festival. Won 135lb weight class division.

Goals for MBA:
Make a full shift to the Social Entrepreneurship space. Feel my ideal environment is where technology and social benefit intersect. I want to either start a company or work for a start-up that creates products and services that empower people to fight out of poverty. I realize this is broad, but I'm passionate about products, especially those that have societal impact. Feel that my professional experience, in operations, manufacturing and product development, coupled with my ECs can help me pursue such a future.

Target Schools: Stanford, Haas, MIT, LBS and Babson

Once again sorry for the detail, but if nothing else it served as a good exercise to do some mind puking. Hopefully someone can offer me some general feedback on my candidacy for the target schools. Also, should I just work on my essays or try to boost the GMAT score by 30 to 40 points?
