Will power, determination and motivation I have to supply myself!
I sort of agree with that. I haven't really felt the need of too much willpower. Or rather not too often. I try to avoid the need of it by not letting myself get hungry or too hungry because that can trigger a big appetite or ravenous sort of hunger.
Determination and motivation definitely comes from within and i found that setting myself up initially with lots of it has helped me get through the more difficult moments.
And the longer i go on the stronger i feel my commitment to my rules is.
However i seem to have sapped all my motivation to my diet and haven't got much left for my work at the moment which is a pain.
