I'm someone who fervently studied classical drawing, painting, and sculpture, against the advice of my friends and professors (they told me to stop studying so hard and to start an art career). The problem with over-practice is that you can get caught in mindless habit. It ruined art for me.

It's become very difficult for me to draw pictures that are interesting (if wrong) because I've trained so hard to draw them accurately. It's all by rote.

I've tried to fix it, to rewind. Now when I draw it's with my weak hand, and that has gotten me drawing interesting (if wrong) pictures again.

Another technique I've tried is using cheap materials. I usually get more interesting results from my 3 year olds acrylics than using professional oil paints.

That said, the love of art never came back. That's why, to the extreme confusion of my friends and family, I'm in tech now.
