Why I don't practice for 7 hours a day
Well, I used to practice 7 hours a day in my youth. Although back then I didn't really know how to practice efficiently.
In high school, I was practicing hard and not getting the results I wanted. It was until I reached college where I realized that practicing smart and establishing a daily routine can be better for me in the long run than playing mindlessly for 7 hours.
Here's why I don't practice 7 hours a day
It's physically exhausting
It's physically exhausting for me to practice 7 hours a day. Also, practicing that long might lead to injuries as a result of overusing your muscles and joints.
I lack focus after the 4th hour
Have you ever felt that you do something repetitive for many hours that your mind starts to wander? That happens to me ALL the time. You're not alone! I even tell my students that it's better to divide up your practice into sections if you have the time. My mind isn't focused if I've been at it for 4 hours straight (with breaks). For me, taking breaks and letting my mind rest from the daily exercise I do with my instrument helps me stay on track .
Staying in a practice room won't teach you about the secrets of music
Music helps us understand our humanity. Being a good player is not enough. Knowing the history behind the music, studying the score, and being curious about the composer's life are just a few things that practicing won't help.
Now, there are people who are capable of practicing 7 hours a day. But I encourage anyone who wants to tackle a extensive practice regimen to draft a practice plan to prevent injuries and have smart, focused practice.
I'm gonna go practice now :D
