Rekindled Motivation?

I've been out of triathlon for the last year, but I really want to start back up again. However, when it comes time to actually train, I can't stop finding excuses to put it off. Sometimes they are legit reasons but mostly I would call it self-sabotage. Even signing up for a race doesn't get me out the door.

I know there's no magic pill for motivation, but what are some tips or tricks the could help push me in the right direction?
