Seem to have lost motavation

I started trying to lose weight (this time) January 1, 2011. As U can see I lost about 47 lbs. I got off track during Xmas & can't get motivated again. I haven't really gained a lot but afraid if things don't change I'll gain most of it back like I have every other time. Right now I seem to gain a lb today & tomorrow I will lose it.
There is so many temptation everywhere. I having to struggle right now. I am 75 years old & don't really care if I don't get skinny but would like to lose about 25 more lbs & keep it off. How can I get motivated to continue on this year?
