In need of motivation!!

Hi, my name is Brittany I don't have the best motivation in the world to reach my goals my main goal is to go from my weight right now 152 and get down to 120 i am 5'3.5" I have two kids so that did some damage. I have a cruise coming up in April and would love to have a bangin body. I just want to be more confident and happy with the way i look cause confidence is sexy!! :) Any pointers and feed back would be greatly appreciated. :heart:
