Also, take notes. When I have people beneath me and I meet them briefly to explain some deliverable or anything I need off them, I do expect them to take notes. If you listen empty handed, I'll be inclined to think you'll forget something. Mind you, don't overdo it. You should understand well enough what the task is just by listening and use pen and paper and whatnot to help your memory, not your understanding. Writing absolutely everything, understanding nothing and then trying to understand later on from your notes is not the best either.Basically, try to work a bit as a waiter. You might hate the comparison, but it does work. If the list is a bit long, consider reading it back to your manager before you go to ensure you haven't forgotten anything and that they've been clear.Also, don't forget that, inevitably, people do form their opinions on you based on subjective perception too. So, again, at least look eager and professional as much as you can.
