THe most important is to be stoked, whatever you ride or however you ride.
Forget the confidence thing, work on being a more competent rider. At first it's difficult to handle speed so people spend a lot of their ride controlling/shaving off speed. But as you're able to handle more speed, you can make better carves because your attack angle is not against the terrain (you are riding down the hill, not across). Also with rocks in the way, you need to plan your line before you drop so you don't have to work slowly down the hill. You examine the line, see where are the danger points are, where you can flat out and where you need to do a big carve to get rid of speed.
