In a nutshell, do the opposite of what you think you should do. If you were balancing a pencil in your hand, you would move your hand in the direction it is leaning to balance it. For a top, do the opposite. Move your hand in the direction the tip is pointing, which is the opposite of the way it is leaning. Since the top precesses (leans in a circular motion), the ideal corrective movement is somewhat circular, but for now, pick one direction to wait for and move it then… like wait for the tip to be pointed the same direction your thumb is and then move your hand in the direction of your thumb.
