"They" say keeping a journal and recording your thoughts/progress along the way helps. However, one fatal flaw that I see is that keeping that journal requires motivation in the first place!
I'd say try that, what's to lose?
Do you live far away from where you work? If not, perhaps you can walk/jog/bike to work? This is if your job would allow it (having to wear a suit would probably prevent you from trying this). Or, perhaps you can wake up a bit earlier, and jog a short while before you go to work, works wonders for "alertness," and starts the day better than a donut and cup-a-joe. The reason for the suggestion is that you HAVE to go to work, am I correct? In linking this activity to something you HAVE to do, every day, perhaps the idea will kick in, and this will become natural routine for you, just as waking up every day to go to work is.
