As someone who has struggled (very, very hard---high test scores, terrible grades, the whole bit) with this, I have recently taken the following approach:
1. The battleground is not a single choice or moment, but all of them.
2. There is a tendency to conflate results with character. If I have not done laundry and am wearing dirty clothes, am I a) a slovenly person, or b) a clean person who has not done laundry recently? The realization that I had no deep, abiding character flaws to address, that I could shortcut the entire "problem" of "fundamental laziness" by achieving the administrivia of life, was/is extremely encouraging.
3. The concept of "time capital" has been a good hook on which to congratulate myself, giving dopamine rewards. Basically: washed dishes are a form of wealth just as much as is money in the bank.
4. Reminding myself that no spectactular effort is reuired, that rather consistent and low-intensity effort is the key, has been helpful. I've always been good at high-intensity tasks---sports, outdoors, crunch time---and much worse at low-intensity ones. On the one hand it is something of a "life sentence" to realize that there are fewer opportunities to goof around, but it is ameliorated somewhat by realizing that the sentence is light labor, not hard stuff.
I would love to talk more about this---my life has had significant difficulties because of "laziness" and seems to be turning around at the moment---but some of those elementary tasks call right now.
Edit: Later. One of the big obstacles, I think is the ethereal nature of the problem. How does one "do" "not-laziness?" What is the momentary choice one can make that will beat the thing once and for all? And what possible paychological reward can there be for staving the spectre off for one more day, knowing that it will simply return tomorrow?
The 80-iq change of perspective, imo, is the mental action of asking oneself: "What can I do in this moment that will advance my goals?" (as opposed to: what can I do now that would match up with my mental image of what a "disciplined person" would do?) This gives you something concrete you can do now, and frames things as to offer a carrot rather than a stick.
One notable thing about this approach is that it often results in less work, as you realize that such-and-such task, while "virtuous," will not actually help you advance your station in life. This can actually be somewhat terrifying, as you worry that this is actually some trick you are playing to get out of work. I guess the sum-up is: don't fall into the trap of morally judging yourself as "industrious" or "lazy." The virtues to cultivate are judgment and efficacy, exercised consistently, not "industriousness."
