A sensible move...?

If you're a working adult, would setting aside 2 hours a day for violin practise be an unreasonable demand on self? I hope you agree, that it is a possible task because I have decided to sit for more violin exams this year. That's right, I find it difficult to improve without the threat of exams looming ahead. So it is because of this ( and perhaps the need to move a step ahead of my competitor a girl less than half my age who has to sit for her grade 5 theory in 2010 and as a result will not sit for the practical exam....) reason that I am subjecting myself and my poor teacher to stress levels high enough to cause some white hair ...and peptic ulcer.
