Then by that standard. skill in other things include:

PvP - know what to use when opponent uses X ability to counter it, if not use y.
Golf - know the course, remember the angle and strength for swings, use the right club for the appropriate sitiuation.
Tennis - know your angle and strength when hitting the ball, have good reflex on where the ball get return to, and hit to the hardest place to return.

Everything in life get boiled down to: knowledge of what you are doing, good reflex on changes, and a perfect execution. Even the ever so skillful PvP is pretty much a combination of that 3 elements.
