'Hanging on' just for today while doing nothing to learn tools to get free of lust is nothing but a bastardization and poor usage of the old adage, 'One Day at a Time". Spare me of that fate, please. I want to surrender lust one day at a time, not hold my breath and pretend I am overcoming it.
There is a beautiful line in the White Book in a short intro piece titled, "The Problem", and it goes like this: "the only way we knew to be free of it was to do it." I have always found it very profound and also helpful when I have a desire.
When I get a stupid idea like "Yep, following her or getting a better look at that would really help me out" and it doesn't just go-away after I say no (which proves to me that my body really believes that it is good for me, in fact, that my body innocently and honestly believes that I need it; exactly like I am convinced - by my stomach - that I need food when I am starving), I ask Hashem to help me remember that there will always be yet another stupid lust image/fantasy/pretty lust object out there later, so 'getting over' my current desire by 'doing it' will not do me any good, at all - the exact same feeling that 'I must have this' will return. Nothing will have changed at all.
