literally you have to practice 100s of times, and eventually you'll get it.
One thing is to imagine yourself landing the trick. Watch videos of people ollieing.
While imagining landing the trick watch the bolts and get your feet to land on the respective ones.
Try jumping forward too.
good luck don't forget to have fun
Commit, that's one thing that a lot of people don't do and, in result, never land the trick. Committing means to just try your best and not worry about falling or getting cuts. Pop the back tail, pull up from the middle of the board to the top and gradually, while in motion, bring your back foot onto the back bolts of the board. Practice, and if you're new, start stationary on like carpet or grass if you're not ready to fully commit to the trick.
Practice
Your body is just scared to land on something that isn't as stable as the ground is but just convince yourself you won't fall, if you do fall oh well, it's pain, pain is temporary. After you're able to do it though, you'll be able to do it forever.
