Truthfully, there haven't been any crazy hurdles I've had to get over since being at Juilliard. Usually, it's just a lot going on at once at multiple points in the year, which for any given Juilliard student, can be/is a LOT.
For example, at one time, I've had:
3 separate gigs
AND a big research paper
Due all in the same WEEK!!
In the end, though, it's ok! After all, we are all performing artists, a little pressure is good. ;)
