I have the same problem, I don’t have enough motivation…
You say that you never get to HI, could be that you’ll never see it! Don’t get me wrong, it’s just that not everyone has HI. Some people have sounds, vibrations and some even smell or taste something (kinda rare) instead of imagery.
That doesn’t mean that they can’t do WILD, you just have to change it a bit. If you get vibrations/falling feeling you just have to stay calm and wait until it’s over, then you could be dreaming 
But it could of course just be that you fall asleep before you see HI, so no worries.
If that’s the case, you should try leaning your hand up the wall or something, so you won’t fall asleep before seeing it. If you fall asleep, the arm will fall as well.
If you want to try a method that may suit you better, I would suggest FILD
Ps. Some call it HILD since that’s the original name, but some people mixed it up with Hypnosis Induced LD, so it was changed to Finger Induced. It doesn’t say anything about on that link (at least not the first page), but I read it on Dreamviews’ forum
