Read Stick and Rudder. It is worth the money and it will give you those Ah Ha moments when true understanding arrives.

Have Fun
Prepare before each lesson and know what is going to be covered in that lesson. ASK ASK ASK questions...this is how one progresses from just demonstrating an exercise to understanding why you will need that skill as an aviator. Have Fun
Ask to move on to the next exercise when appropriate skill has developed.....no need to keep dual instruction until perfection, when you can practice that exercise while solo until perfection. Have Fun
Fly very very often especially up to the solo to prevent much instructor repeat/review while in the air. Have Fun
Keep your head on a swivel, your IAS up, and did I mention HAVE FUN?
