Personally, the only success I had in finding someone or going somewhere OOB is with intent and desire. I have to REALLY want to go there, with all my mind. I think really hard about the person or the place I want to go, and I imagine moving in that direction, but without actually moving any of my "astral" limbs. I then feel a sensation of movement and I find myself floating where I want to go. (Usually, if I don't get side-tracked). It's also important to keep the intent in your mind until you reach the destination and not drop it when traveling.
Hope it helps.
