Hi,
Im 18, and have left school this year after finishing 6th Form. My problem is that wherever i go, people get the inmpression that im a bit 'dosey' or dumb. I'm always mishearing things and making myself look stupid or clumsey infront of other people (this is especailly embarassing where i work)
I worry that people take the piss behind my back, as i know they take the piss out of other people behind their backs...
Its like im constantly having to remind myself, 'dont do anything stupid' all day long, but then my mind drifts and i forget and make myself look stupid again

I know its probably nothing really much you can do to help as its not your 'normal' everyday-problem, but can anyone advise me how to play it cool?
Would really appreciate some tips!
Thanks!
EDIT: Forgot to mention, i've only ever had this problem at work though...
