How's Your Opening?

Eric Schiller says (http://www.chess.com/chessmentor/view_course.html?id=289), "I often refer to "the opening guidelines". By this I mean the four rules which will generally get you through the openings

1. Place a pawn or two in the center
2. Castle!
3. Connect your rooks
4. Aim your rooks

When you aren't sure what do do, think about those four goals."

Evaluate your opening by these four guidelines. How are you doing? With which of the four do you struggle the most? What can you do to remember that guideline more consistently?
