I definitely agree that long term follow-ups are important.

For me the best productivity hacks aren't adderall/redbull/caffiene pills, sleep cycling, standing up or locking myself in a hotel room. And it's not knocks on those methods per se, its just that I have a very hard time doing them with enough regularity to be relevant.

The best productivity hacks in my experience are still simply staying positive[1] and hiring interns.
