A Smooth Gate

If I get coffee in a typical porcelain coffee mug and then try to walk to my office, I will invariably spill it on myself. I wonder if it's just me, or does everyone have this problem? Are you supposed to fill the mug low so this doesn't happen, or are you expected to walk smoother? Do I have a rough gate? I decided, this morning after spilling all over my hand and cargo shorts, to attempt a smoother gate. I realize the reasons for a smoother gate can be much grander, for instance, a wide receiver in football needs a smooth gate so that he can keep his eye on a pass intended for him as he runs full speed toward the end zone. I just want to be able to make it to my office without sloshing coffee all over me.
