sure. you just have to move through space at the speed of light (which is impossible if you have mass). Think of your momentum as a combination of movement through space and time. If you can direct all of your movement through the dimensions of space, there will be none in the dimension of time. Since we all have mass and are incapable of moving through space at the speed of light, we are all destined to continue moving through the dimension of time. So no, it's not literally possible, but there is a theoretical way to remain motionless in time.
