There are similarities with learning to drive. Remember when you could not even steer in a straight line? All that frantic over correction etc?
Do you think about it now when you drive? I doubt it.
Flying will be just as overwhelming to start with. First you have problems with basic stick & rudder, then takeoffs, then landing etc etc but after a while you won't even remember what the fuss was about.
But lookout is an absolutely essential habit which you do need to try to learn from day one. That's why your instructor will be very keen for you to fly by aircraft attitude and not instruments.
Don't worry, it'll all come together (as the actress said to the bishop)
