I'm pretty submissive, which is not a good trait to have. I coach younger kids at my tennis academy, and when things get out of hand, it's very tough for me to wrangle them up and discipline if necessary, because I'm naturally shy and not an outspoken guy. After a year of dealing with the annoying youngsters, though, I've noticed that this summer I'm much more accustomed to yelling at them if they're doing something wrong, so I guess it's improving, haha!
