On steeper terrains, my issue is
2. I freak out to imitate the toe side turn. I know I'm on the back seat, but I cannot for the life of me to lean down the slope because I'm afraid of gaining speed. What can I do to overcome this fear? Sometimes when I do have the courage to do so,I out weight on my front leg while keeping my rear leg heel edge dig in, the boards starts turning and it turns beautifully, but that's when I'm possessed and not freaked out.
What can I do to gain more confidence?
The fear is natural. A big factor into it is the fact that you're not used to the speed yet. With time, experience, and practice you'll continue to get better. A progression of getting better also means you're able to handle more speed. Take it slow and continue to learn. As you learn to control your board and learn to feel your edges you'll be able to gain confidence in your riding abilities.
