I did the same thing every year with my New Year's resolution. To get physically and fiscally fit. So this year I read something about putting it on the calendar and it would be out there in the future, so I made my goal in January for my birthday in November and wrote it on the calendar in my spare room and tried for it.
I didn't quite make it, but I got farther than I have in years and actually am confident that I will get back to goal and stay there. Something about having that on the calendar got me through those times when I wanted to just quit after a few weeks and slooooooooow weight loss.
So, I made another goal and wrote it on the calendar and already have my goal ready for next year's calendar. My goal was 145 for my 45th birthday, so my next year's goal will be 146 for my 46th. It'll be more about maintaining than losing.
If I get to my WW goal (150) in the next few months and then can maintain it for close to a year, I'll be so thrilled I won't be able to stand myself
So maybe try writing something down on your calendar a few months from now, it doesn't have to be huge, and give it try. It wasn't my idea, but it worked good for me.
good luck!
