Composing Mozart's Side Hustle

i grew up playing classical violin, so i have played a lot of mozart pieces. And you would think from my perspective, i always thought he must have just been completely devoted to composing. But he totally was. compose was a side hustle for him. He was trying to pay the bills with all the other stuff. Maybe the perspective to take away from that is, well, if he could do all this stuff on the side, then it's not too late for me either.
