Try to simplify the mechanics in your head. You can hear how to ollie from a ton of different people. One of the ways they say to think about it will click for you.
I think about it as putting my weight on my back leg with my knees bent. Then I think of lifting my front leg to completely put the weight on the tail of the board. Push off the back leg and feel the board help pop you into the air. Bring the board to level mid air.
You'll get it. You just have to get the timing right. When you feel it once, you will always be able to do it.
