I had to transit anyways, and I found it hard to work in transit. In hindsight, I had terrible sleeping habits, and eventually, it forced me to start taking naps wherever I could. A schedule materialized organically and became the norm when I gained the trust of my instructors.

And yeah, it was for a competitive advantage. Not within my school, but for college. I didn't understand how college or scholarships worked until my 10th year, which meant that I had to become competitive much quicker than other applicants.

On a side note, the worst periods were phasing in-and-out of schedule during winter and summer break (I worked a 9-to-5 on breaks), which I did three or four times.
