I guess I have a slightly different take on this subject. I don't consider mundane tasks to be boring, to me they're just tedious. For me, boring is things like sitting in a waiting room waiting for an appointment with nothing to do but wait. I don't have one of those personal electronic devices that people refer to as a "phone" these days, so I don't have that to occupy my mind while I'm waiting. Often enough, none of the magazines are interesting enough to read, so I just sit there. That to me is the meaning of boring.
I'm thinking that maybe... something that is boring is not inherently tedious.. but something that is tedious is always boring... maybe?
That seems like a quite reasonable assumption.
