Well, I don't even know if meta is the right place to ask this, but I thought it suited more than the standard Math Stack Exchange.
As a mathematics undergrad student, I usually face some questions more related to the "math lifestyle", such as: "how is the daily routine of a researcher mathematician?", "should I be studying more of this or that?", "is my way of solving problems a good practice?". I know that these questions are not appropriate for MSE, since a good deal of opinion is involved, but I believe getting in these "soft" discussions and talking to more experienced mathematicians can sometimes do just as much for your professional development than looking for answers to specific math problems.
So I am here for recommendations of other sites, forums or groups where I can discuss these themes more freely. Thanks in advance.
