That is EXACTLY what summer break and weekends are for. How do you plan on getting better? Whether it is the trumpet or the sax, you have to practice more than other people and smarter than other people. If not, you're going to be average (or worse). Do star baseball players not practice between seasons? Don't football players run and lift weights. There are no college scholarships for video games or screwing around. They, do however, give them for music. Or be mediocre. Not that is not to say you shouldn't have fun. But weekends are long. Giving an hour or two to practice will not ruin the weekend. Giving an hour a day during summer break isn't much either. But both would make you a much better player. I am working three jobs (Music Minister, Brass Store Owner, Part-time Licensed Psychotherapist) and I can usually get an hour or more a day in. I still enjoy life outside of music. I also love to practice -- I love making music! Shoot for mediocrity and you will probably achieve it! That was part of the message in the article (although not in those words). You cannot be great at everything, but whatever moves your soul and where God has blessed you with talent, you should strive to excel!
