It's commendable that you want to pass on wisdom. But I suspect your daughter isn't going to miss your wisdom anywhere near as much as she's going to miss you. What is it that makes you so uniquely you?
For example: I have some really strong memories associated with science fiction, particularly Poul Anderson's Tau Zero. So I might record myself reading Tau Zero, and whenever I reached a passage that really resonated with me I might go into a long digression about why it resonated with me, and things in my life and history that also strike that same thematic note. By the end of it, she would know not only that I loved Tau Zero, but she'd know a lot more about me and why I loved it and why it spoke to me and why, with only six good months left, I'd choose to spend six hours of it recording it for her.
Wisdom is overrated. It really, truly is. It's valuable but it's not the best thing out there. And I say that as the son of a father who has the keenest mind I've ever known, a guy who has enormous life experience and wisdom and has shared it with me freely throughout my life. If-and-when he goes, I'll miss his wisdom a lot. But I'll miss him more.
The most important gift you have to pass on to your daughter isn't your wisdom. It's you.
