I taught my daughter to fly when she was 9.....
Always anticipate the need for power (throttle) it's easier to pull back power when not needed, than to apply power when you need it...
I'll explain...When I teach anyone my throttle is rarely below 1/2...takeoff, landing, and approach training I am always at full throttle. This way if the student gets into trouble all I have to do is fix the attitude of the airplane, power is there....If for some reason power isn't required then all I have to do is retart the the throttle....
Altitude and speed are life in aviation..
Now go have fun
