Andrew Huberman’s “Goals Toolkit” is responsible for me finally losing some stubborn weight this year, and I plan to apply it to other things I want to achieve.
It's Aug 2022 so a bit out of range for the OP, but his alcohol episode convinced me to really cut down on drinking, from about 2 beers (low variance/rarely drunk, just a homebrewer with a craft beer obsession) a day to a day to maximum 2 beers a week. I sleep better and lost 35 pounds in the last year.
