I had the same question when I started and I know there are some very experienced jumpers who just don' t get this. Not that I am that great, but I understand the concept. Just skydive on the RELATIVE wind. Forget about your orientation to the ground.
When you leave the plane, the relative wind is horizontal from the front of the plane. So, for example if you leave early as a floater, you may need to "track up" to the base or, as a late diver, you may need to de-arch to blow back a bit to the base as well as dive to get down to them. As you pick up vertical speed and bleed off the forward throw of the plane, the angle of the relative wind increases until it is finally vertical from below you. But you really don't have to think about it that much. You do need more exaggerated input "on the hill" because your airspeed is not that fast. There is nothing like turning some points on the hill.
