This depends on your goals for that session.
If we’re reviewing an asset or artifact like a deck or document, sharing it in advance along with your goals and objectives will enable me to prepare notes and advice in advance, which will give you more out of your session.
If we’re discussing a topic, the same applies. Email me with as much advanced notice as possible with what you’d like to talk about, and that will give me the time to prepare links, suggestions, and other tools.
