When I see the title of the thread come up... I usually hit the "all discussions" button, whatever it's called... and see this one... something comes to mind.
When I was a kid, playing my Mozart, Chopin, Tchaikovsky, Beethoven, Rachmaninoff, etc., I had thought I wanted to play in Carnegie Hall. As I grew up and life had its twists and turns, I kinda lost my desire for that. I didn't enjoy that style of music as much the longer I played it. So my childhood dream, maybe it was more of a fantasy than any actual goal and perhaps I might not have really wanted what I thought I wanted.
Later, probably in the 1980's, I was much more into radio, including talk radio. (Of course there was NPR and Marian McPartland on Saturday nights. But there was also a guy on most night named Bruce Williams that I particularly liked. Practical advice on most everything, usually business related. He often spoke of a son who played piano down in some of the establishments on Bourbon Street, in the French Quarter of New Orleans. He built quite the romanticized version of the place in my mind.
Fast forward 20 more years, and I married my wife who just happened to live not far north of... New Orleans! Guess where I wanted to go? Bourbon Street! Somehow, it was not the place of my dreams at all. Didn't like it. Had no desire to go back, ever, and so far, never have. (Moved away from the area after Hurricane Katrina.)
So... "If you're aiming to become a concert pianist"... not anymore. For a very few, it may be wonderful. Not really the road for me, though. I doubt I'd be very happy there in real life. Fantasy and daydreaming of the standing ovations are great. The rest of it? Dunno. It may not be what most think.
