The math does not check out here:

> When I share recordings with family and friends I often hear that I’m talented and people are surprised that I only play for a year. I have much worse opinion about myself, but take the compliments with gratitude.

> Here I’ll share the secret with all of you. The open secret that I tell to everyone who asks: I play piano 1-3 hours per day. As of today that’s probably ~1000-1500 hours.

1000 hours in one year is 2.73 hours per day. 1500 hours in one year is 4.1 hours per day. And that's 365 days in a year.

If you drop it to 250 (say M-F), it's 4 hours per day (1000) to 6 hours per day (1500). If that's dedicated time, that's more in line for a full time job (or at least the portion you're actually doing constructive work).
