Strategies To Lose Weight Fast

Im going on a cruise at the end on April 2010 & i would love to lose about 30 pounds so i could look great ! I am also starting school in about a month and its going to be hard to workout , have school work , & carry a job at the same time. Are the any tips to get me motivated to lose weight quick and easy ?

I would love to lose weight more in my thighs & stomach area !
