Is it advisable for a graduate student to work as a freelance copy-editor (for few hours a month, for papers in his/her area of interest)?
This topic emerged a few days ago during a conversation among a few colleagues of mine; we came up with the following upsides and downsides:
(1) increased financial independence;
(2) valuable training.
(1) possibly time consuming and stressful.
Is there any other upside or downside we may have overlooked? (For example, could this kind of experience turn out to be a positive addition to an academic CV?)
