TITLE: Advice on changing topic for thesis problem
QUESTION [19 upvotes]: I am starting to find my thesis problem not meaningful nor interesting and too technical.  As I learn more mathematics I am finding myself attracted to other topics and only started on my intital problem with my advisor because I could understand it at first.
My problem is a very "good" one, fulfuling many criteria mentioned by mathematicians:

It is pitched at exactly the right difficult.
It involves learning a big machine
It solution leads to further work and questions. 

Should I:

Find a new problem? (I'm sure I can't think of such a "good" problem as the one given to me by my advisor.)
Stick with the same problem and only do new problems after graduation?
Anything else?

REPLY [10 votes]: My advice: find someone who knows you in person, and knows more about your situation to talk to about this.  The best would be if you felt comfortable discussing it with your advisor, but another professor you know, or some sort of graduate subchair, or even an older graduate student would also be good.  You just aren't going to get anything but the most vague advice that's not very well-suited to your situation from strangers on the internet.
