is practising 5-7 hours a day practical? Wouldn't you be exhausted/tired/mentally tired etc? Anyways, keep practising hard and don't give up on your dream.
Oh, I just wanted to know the opinion of pianists, to have a realistic point of view
Can i be a good pianist? What does my future expect?
As it has already been said, it depends on you.Do what you like! If you are passionate for the piano, do your best!P.S. Personally, I believe in this: If you want something, if you really do, then you can achieve it!
I will stick with this, thanks for your comments
