There are so many opportunities to make yourself into the violinist you want to be.
The key is to find a balance in chaos and order.
Practice daily. And do some things within that practice the same way every day. Spend a week or two warming up with scales. Or a month or seven working on the same piece.
But always look at it differently.
Ask yourself why you are practicing what you’re practicing. Ask yourself how you could do it differently. Look up tutorials on the specific subject you’re studying. Get violin lessons from different teachers. Ask your friends for feedback on what your doing.
Look at the same subject with fresh eyes every day.
When you can’t think of a new way to look at the same thing with fresh eyes, then it’s time to move on to something new. And who knows, after you’ve done that new thing for awhile, you might have fresh eyes on the old subject all over again.
