This is a simple guide showing you how to interact with someone more accomplished or more well known than you.

• You need to get to your point extremely quickly, and provide some sort of value.
• Don’t act like a scared cat, you both have brains, your both human.
• Don’t ask about things they have already talked about a million times. Do your research.
• If you give respect, give it in a specific form.
• If you ask something, ask it in the most specific way possible.
  (the more you ask, the less reply you will get)
• Get right to what you think can add to the conversation, or where you think they were wrong about something, or where you think you see an additional point.
• When writing short emails, write no more than 3-5 lines and around 100 words.

So to summarize this:

1. Don’t waste their time.
2. Don’t grovel.
3. Be specific.
4. Add value.
5. Be concise.
