Another thing that really helps, is before you hit the feature, imagine yourself, in your head, hitting the feature and how it's going to play out. Run it through your head, your speed, ollieing, riding on the rail, and your landing.
What this psychologically does, is since the actual act of hitting a rail happens so fast, when your new you have no time to really think about what your supposed to be doing when you actually get on the rail. By envisioning yourself doing it, it kind of gives your body a guideline on what it should be doing even if your brain is going "woah!"
I'm new to park as well, but when I've done this before hitting a feature, I've had a much more positive experience either landing it or getting close.
