Doing anything that moves the needle is hard. All the "I resolve to do this and that (eat more kale / break a sweat / cook more / drink less)" business requires so much diligence and determination that, by now, most resolutions are on the cutting room floor. I used to have a cartoon on the magnetic face of an old file cabinet, "At least I am protected by the goodness of my intentions." You know what? No, I'm not - and you aren't, either. Good intentions do not move any needles.
