You will get used to it.
The best thing you can do in your case is to face the way you are taking off so you still see where the plane is heading. Watching your plane and the runway some times keep your mind off spectators. Block out the ones behind you and make sure there is no one in front. I always face the direction of flight where I can see all directions in the path of my plane. The main thing is to not try to show every one how you can fly, they will see that
