Easy solution is to keep your eyes up :) I've always been told and said to beginner riders that you look where you want to go. The last place you want to go is down :P
Also remember your head weighs quite a bit. If you look down, it's going to influence other features of your body and thus your horse.
Relax. Sometimes when we are focusing on one specific aide, we get tense. You may end up pinching with your knee, tensing up through your hips or just nagging your horse.
Take a nice deep breath, think forward, give him rein and some leg. If he is doing it correctly, don't keep nagging with your leg.
I hope I understood your post correctly...
