In reply to euanryan: Within 20 minutes does sound either weird or worrying. Presumably you are still just starting the walk-in? Don't wear any gloves & bury your hands deep in pockets. At 18yo you certainly don't need to be carrying poles or anything else in hands.
Mitts, especially dachsteins, are where it's at for anything you need to do before kitting up. Before reaching the route do any fiddly stuff like harness, helmet & crampons then walk again to the foot of the route. Do them in more than 1 stage if its getting too cold.
Learn to do as much as possible with mitts/gloves on.
Opting to lead the 1st pitch is always a good one as the 2nd has to chill down from the walk-in while you fanny around (which you should always be mindful of, of course- partners in pain ain't good). Choose a route with a quick 1st pitch & obvious belay to speed this all up; this is easier than it sounds if you think ahead.
Loads more tips are possible but the theme is all about preparation & practice so that the climb's the hard bit not the faffing.
