I'm a firm believer that in order to reach virtuous levels in anything, you really need to take advantage of your teenage years to nail down the fundamentals.
I'm a musician myself, and spent almost every day between ages 13 to 20, often up to 6 hours a day, practicing and playing my instrument. Way more often than not, when I meet very talented people in different walks of life (music, tech, sports, etc.), it's the same story.
Teens also tend to have a very naive optimism and ambition / drive. Nothing is impossible, and no-ones gonna stop them. I think you need that no-breaks mentality to succeed.
And lastly, people naturally root for young people. The next hope, and all that.
