Not the worst advice, the collective wisdom of /. is both enlightening and sad ... depending on who you're listening to at the moment.
My advice ...
1) Teach her that nothing of great value is easy. If it is easy people don't value it. Don't take the easy path, just because it is easy. Don't avoid the hard path, simply because an easy path is available. You'll miss out on what everyone else is missing, and will not be better off because of it.
Things that are hard to acquire are the things people tend to value more.
2) Learn all you can about everything that interests you. Once you learn something, there is nobody that can take it from you.
3) Make things. Build something, anything. Make something that is hard (see #1), take the time to do it right. You'll learn something (#2) and you'll have something of value in the end. And when you're done, do it again.
4) Value people over things. Don't get attached to things, get attached to quality people. Things can always be taken away, but nobody can take away a friend. Not time, not distance, not anything.
In the end, there is nothing from this world we can take into the next. The only thing we leave is a bit of ourselves behind, in the lives we have impacted, and the things we have built.
