My mantra is one day at a time because that is what has gotten me to where I am now. I have even tried taking it one choice at a time and that has been successful for me. I think of them as "little victories"
I choose each day to work towards feeling and looking better. Some days are harder than others, but if you take them in even smaller pieces, like I choose to use small dumbells while watching tv so that I can do something I want to with something I don't. Hang in there, it is a slow and steady pace. It has taken me 10 months to lose 20+ pounds, even though my goal was to lose 50 by my 30th bday in Sept. When I had to go buy clothes in a smaller size, I was rewarded for all of my little choices (ie. cook at home, instead of fast food, or switching to Diet soda)
I hope this can be a little encouraging for you, you deserve to obtain your goals.
