I don't know enough things yet.

One reason you might be disappointed with Altman's list is that it doesn't seem earnest. I think it's a great list of things to know, but I'm not sure it's the list he'd hand to a younger self and expect it to land. Many of them are cliches and probably had been told to him. They just require more experience to appreciate.

Great advice is generic and borderline axiomatic. These are all rather specific and easy to dismiss as being non-applicable.
