Hahaha, when I have things I absolutely must get done, I pretend to myself for that time that I am a movie character that is really responsible or ambitious, like Tracy Flick from "Election". It works for me, because in my head I don't think I am doing boring things, but rather I'm acting!
Post-its - helps as long as I don't ignore/lose them
Lists when I go shopping - helps to not forget things
Calendars - help a lot...I missed a concert I bought a ticket for recently because I didn't mark it on a calendar
Being on time - I have to get up / start getting ready about an hour earlier than I think I need to
Also, I try to not visualize completing my goals, because then I feel like I already did them & then they're even more of a drag. Instead I just dive into it, and usually put music on so it feels more "fun".
