I hope I can find some support or modifications to my brief plan. I weigh about 169 (I'm 5'4) and I am ready to start losing weight. I just need some motivation or words of wisdom to know that what I am doing will result in weightloss and that I am not wasting my time!

So prior to today all I did was study (I'm in school, finishing spring class in a week). My new plan consists of playing soccer sometimes 2x a week and adding in Jillian Michael's 30 DS maybe 2-3x a week. I also am trying to get outside and bike ride, walk my dogs quite a bit as well (that total a week would be 120 minutes at least).I will hopefully be getting a part-time job in a couple of weeks so that should keep me on my feet as well.
Meals-I have been eating less than I used to(healthy way of course). And cutting out needless snacks.
SO!! My question is--will adding all this help me out in the long run? My goal is to be down to at least 145ish by August. Would you suggest to add anything? (meal wise, exercise?)
Thanks for all your help.
