i am the exact opposite. ha ha ha ... once i get going on a problem, you could fire a cannon next to my ear and i may notice. as a matter of fact, i prefer noise around me when i'm working. i'm not being sarcastic. i'm pretty good at my job, although no genius (not even that smart) by any stretch in any way :)
but i feel that this ability to hyper-concentrate helps me overcome an otherwise average intelligence. anyone else experiences this?
