Don’t explain [the concept] to me. Instead, throw me straight into a real-life situation where I have to write it and probably make mistakes. If I make a mistake, don't give me the answer. Ask questions that force you to discover where your reasoning falls apart. Please reply only after I have tried at least twice. Repeat this cycle until I can guess correctly without hesitation.

The following is confusing to me. Before I explain, please tell me: What is that one sentence that if I understand just this one, the rest will take care of itself? Just explain that sentence first. Use everyday analogies without jargon. Then ask me three questions that only someone who really understands can answer. Don't move on until I pass all three. [Paste content here]
