They are hard for me too! One thing to is to make sure you are looking past your wheel. I find on hairpins for some reason I tend to get focused back on the front wheel. Otherwise, everyone is right slow drills to get the poise will help. It takes time to get comfortable with something like this, they just feel awkward and scary!
