Only music high school,not university.
But the truth is,most of my practicing I did during elementary and high school,
luckily(read sadly if you wish) I had nothing else to do...
I did attempt Music Academy for one year but there's no guitar department so I quited,
I loved all theory stuff etc but it was too much of piano for me at that point.
I've heard that Academy does have guitar department now but only classical,
which just isn't my way of living.
So after quiting Academy I went into pro's,to make a living of it
and that's when practicing usually stops I'm afraid to say...
I'm not talking of famous pro players,giging topics and schedules
push them to practice all the time,
but when you're local pro player(hired gun) then you have to do/play
many things that you don't enjoy a lot,and it's all related to music.
Still,I'm trying to keep further and build myself,
not to stay on current level,something like that.
Thanks for your interest Pavel,hope I explained it a bit!
By the way,try to spend educational part of like as better as possible,
later on you'll see that many responsibilities are standing on our ways,
I've found that educational part the best,good luck!!
