It messes with your memory severely and the more you use the power the more severe a temporally caused form of schizophrenia you develop becomes as well.
If being stuck in place was not the side effect of this superpower, I would assume that you would be able to move because the force you can exert is greater than the force of static resistance that air has.
However, since the air can't move, every step you take would create more and more of a vacuum behind you.
So you could pause time, walk six feet, and create a massive sonic boom that would shatter glass in a several meter radius and probably throw you to the ground and potentially rupture your eardrums or give you soft tissue damage.
You could defeat enemies by freezing time, punching them a couple of times, and then walking around them until all of the air around them for several feet was missing, and then retreat to as safe of an location as possible, and then unpause time.
If you got onto a bicycle and peddled several miles, you could cause widespread destruction.
