Who grew up with a lot of noise in the house from people, TVs or even a radio blaring music (or a record playing at a danceable level?) I thought that was a great way to be 'tuned into life and get motivated to learn stuff' and could do homework with that racket going one. But by third grade I realized I'd have to have a quieter place to study at my desk and do my homework.
I took it upon myself to set a bedtime that made sense, get my homework done and keep myself on track.
