It depends on how quickly you want to "get it". If you are still sinking with superman glide, I would work more on superman glide until the only thing that makes you stand up during a glide is that you run out of breath. At least make that a goal. It is possible.
If you want it badly and soon, stop, stand up, regroup, and start again. Sure, it will be frustrating at first, but it will improve as your body learns balance.
