As some of you know, after many years playing viola and ultimately getting bored of the repertoire, I decided to pick up a violin recently

The problem is, now that I've been playing it... I actually want to get better! I got to a reasonably high standard on the viola quickly, but because I had no patience when I was 11-14, and later on very little motivation/inspiration to improve on the viola, my technique is filled with holes

I haven't had a lesson in more than a year, and even for the last 1.5 years I was taking lessons I wasn't very serious about it

But I've been listening to lots of violin music lately... and the idea of being able to play the violin properly is very

(and it has been for years... I just never took the initiative to acquire a violin) So now I have this urge to sign up for violin lessons when I start at university... and I know the teachers will be very, very good, and I would get a lot out if it... but I would feel really guilty because violin lessons would be twice as expensive as viola lessons (because I'm a violist in the university orchestra, viola lessons would be subsidized), and I know the viola teacher is also relatively good. The problem is that I'm much more interested in violin repertoire, and even cheaper viola lessons would be wasted if I'm not motivated to practice... I can afford lessons either way, but I don't want to make an irresponsible decision. Any thoughts?
