Within 3 months of attending a CFAR workshop I had left my job for one that I preferred and that paid 15% more. Within 6 months I had started exercising daily (previously once every few weeks), waking up consistently at 6am (previously varied anywhere from 8-10am), and eating significantly healthier (I also started eating vegetarian meals 2-3 times a week, previously 0). Independent of any of these concrete behaviors, I now have a very strong belief that I can intentionally construct/change my life and behavior in ways that will actually work.

Post hoc ergo propter hoc, etc. I have a fairly strong belief that attending a CFAR workshop and interacting with the alumni community has been at least partially causal in me improving my life, but I don't think any of what I've said constitutes good evidence of that claim.
