Heh. I'm about to sound like a broken record to anyone who has been around for a while.
Here's what it took for me: The realization that this is Not Optional. Eating healthy, exercising, taking care of myself is not something that I get to decide if I
want to do. It is simply one of the things I
do because I'm a responsible adult.
I get out of bed every morning and go to work - even though I'd much rather snuggle down and sleep until noon.
I pay my bills even though I'd rather spend my money on shoes and massages and dinners out.
I do laundry and brush my teeth and clean the toilets and mop the floors - all things I'd much rather just skip over if I could.
All of those things are just part of life and things you do when you're a responsible adult. You don't really have a choice to say "no I won't do this" because it has to be done. You can't make excuses to the mortgage company - they won't listen to "I didn't feel like it". You can't make excuses to your boss or clients - "I didn't feel like coming to work today" just doesn't cut it.
And I exercise and eat healthy because I don't have a choice to say "no I won't do this". It has to be done. "I didn't feel like it" just isn't acceptable.
For me, that helps a lot with the whole "motivation" thing. I don't have to be "motivated". I just have to do it.
