Time

@elijah thanks for your question When we're first learning these techniques, we take out time and focus on gaining a substantive understanding BEFORE we address timing issues. Once you become comfortable with the material, you'll find that the more practice diagramming, you'll be able to do it more easily and in a shorter amount of time. After a while you also won't feel like you need to diagram every question, and that's okay. Nonetheless you will always find some questions which you do not immediately understand without diagramming them.
