as shallow as this sounds it's usually big social events that motivate me

like weddings where I'll see family members I haven't seen in a while

or holiday get-togethers with old college friends

or vacations

or an annual Ball we attend, and I have to get into that evening gown!

I usually figure out how much I've put on due to sloth, how much I have to lose, like say 6-10 lbs, count back the weeks from the event and put myself back into Induction till the Big Day (or Night)
