I think it's important not to confuse #3 (Think like Feynman...Imagine actively. Use the phrase “that would mean…” to force yourself to think on your own terms with your own vivid images.) with over analogizing. Thinking about a concept creatively to see a different view is great but only understanding something as something else can prevent one from deeply understanding the concept. Even if one begins to comprehend a concept through analogy I think it's important to eventually think beyond it, and see "through" the analogy to the deeper meaning. Think of leaky abstractions.
