Of course, self-study isn't only a topic for test-prep students. Lately I too have been doing a lot of self-study at home, mostly on development topics. In the middle of that, YouTube — for the first time in a very long time — actually recommended a fitting video, so I'm writing a few lines about it.

For test-prep students, office workers (especially remote), and freelancers, the standard for plans and results should be "volume per period."
For founder-level people, aspiring founders, or creators, it should be "time per period."
For someone who has just graduated or just entered school, or has retired and is preparing to start a business (excluding freelance and service-outsourcing work) or to become a creator, "time per period" is extremely important.
Students, with the college entrance exam, and office workers or freelancers, in a work setting where tasks are handed down from a superior (or delivered by a client) — once they've endured that kind of external-standard-setting work environment for more than a year, they've adjusted to aligning themselves with someone else's standard (or expectation), not their own. So, when they have to steer their own daily life, they need buffer time — warming-up time — for the switch.
It's similar to what the video describes: academy-trained students suddenly being asked to self-study at home and going "blank" for a while.
