Atomic Habits by James Clear:
https://jamesclear.com/atomic-habitsIn Franklin’s autobiography, he names 13 virtues and describes his “fake it until you make it” approach, as boz characterizes it.
My intention being to acquire the habitude of all these virtues, I judged it would be well not to distract my attention by attempting the whole at once, but to fix it on one of them at a time, and, when I should be master of that, then to proceed to another, and so on, till I should have gone thro’ the thirteen; and, as the previous acquisition of some might facilitate the acquisition of certain others, I arranged them with that view, as they stand above. Temperance first, as it tends to procure that coolness and clearness of head which is so necessary where constant vigilance was to be kept up, and guard maintained against the unremitting attraction of ancient habits and the force of perpetual temptations. This being acquired and established, Silence would be more easy; and my desire being to gain knowledge at the same time that I improved in virtue, and considering that in conversation it was obtained rather by the use of the ears than of the tongue, and therefore wishing to break a habit I was getting into prattling, punning, and joking, which only made me acceptable to trifling company, I gave Silence the second place. This and the next, Order, I expected would allow me more time for attending to my project and my studies. Resolution, once because habitual, would keep me firm in my endeavors to obtain all the subsequent virtues; Frugality and Industry, freeing me from my remaining debt, and producing affluence and independence, would make more easy the practice of Sincerity and Justice, etc., Conceiving, then, that, agreeably to the advice of Pythagoras in his Garden Verses, daily examination would be necessary, I contrived the following method for conducting that examination.

He further describes how he tracked his progress.
I made a little book, in which I allotted a page for each of the virtues. I ruled each page with red ink, so as to have seven columns, one for each day of the week, marking each column with a letter for the day. I crossed these columns with thirteen red lines, marking the beginning of each line with the first letter of one of the virtues, on which line, and in its proper column, I might mark, by a little black spot, every fault I found upon examination to have been committed respecting that virtue upon that day.
See p. 39 for his table: https://www.ushistory.org/franklin/autobiography/page39.htm
I determined to give a week’s strict attention to each of the virtues successively. Thus, in the first week, my great guard was to avoid every the least offense against Temperance, leaving the other virtues to their ordinary chance, only marking every evening the faults of the day. Thus, if in the first week I could keep my first line, marked T, clear of spots, I supposed the habit of that virtue so much strengthened, and its opposite weakened, that I might venture extending my attention to include the next, and for the following week keep both lines clear of spots. Proceeding thus to the last, I could go thro’ a course complete in thirteen weeks, and four courses in a years. And like him who, having a garden to weed, does not attempt to eradicate all the bad herbs at once, which would exceed his reach and his strength, but works on one of the beds at a time, and, having accomplished the first, proceeds to a second, so I should have, I hoped, the encouraging pleasure of seeing on my pages the progress I made in virtue, by clearing successively my lines of their spots, till in the end, by a number of courses, I should be happy in viewing a clean book, after a thirteen weeks’ daily examination.
