<p>Ok, it’s not exactly my business, but you listed homework as an extracurricular? I get studying while playing (we’re talking about revision here right? Because playing piano and doing written homework is, to the best of my knowledge and imagination’s limits, impossible), but I don’t see the need to axe your piano hours in half for that purpose.</p>
<p>By the way, though 200 hours is possible in theory, I fail to see how it’s possible in reality because you’d need to be doing at least 3 activities at the same time to get to that goal, after removing sleep hours, and even more after removing school and studying. Unless you’ve got a time dilator at hand…</p>
