Each time you meet with your protege, record the date of the meeting and the topics you discussed. Also note future items to return to or follow up on. This will be an excellent record for you and your protege, as you seek to cover a huge range of topics. Your mentor manager may also ask to view the log periodically.
Either download a copy of the mentor log (attached below) or track this same data in your own files. The format is less important than the content.
