i'm going through the same problem right now. gonna be starting university after summer and have been stressing about how i'm gonna get my name out to all the people that will be asking me. So far the best technique i've discovered is to start with "my name is" which fills like a nice jump-start to the name, so instead of saying "a,a,a,a,aaaaandrew". it will be "mmmmynameisandrew"
