My only tip is "HEAD AND EYES."
Whether you're on a motorcycle, driving a car, riding the slopes or surfing, it's all about your head and eyes. I remember a thread a long while back about you getting a Buell, so you might be familiar with this principle.
I find myself chanting "head and eyes" on my bike sometimes, because it's so true. Where your head and eyes are looking, your body will go. If you're looking through a corner, you'll make it through the corner. If you're looking down the slope, you'll go down the slope. It's subtle, but where you turn your head and eyes determines where your shoulders and and arms go, where your core goes to balance you, and ultimately which way your legs turn. As you're getting up on the surfboard, look where you want it to go, not down at the water. If you look down at the water, you'll go into the water.
