Keep your eyes outside. If you're being a good private pilot flying VFR you should get nearly all of your info from the outside. Turns, climbs, straight and level etc and all be done with only momentary looks inside to check your engine instruments and the 6 pack.

What does this do for you? By keeping your eyes outside and scanning you're not micromanaging and seeing every single small change in the aircraft. It also makes you a good private pilot.

I got sick the first couple times. It was a combination of the excitement and issues I've always had with motion sickness (I still don't like riding in the back of a plane or car). I got over it with time.
