How long is too long?

Very interesting comment today by a bright and quite thoughtful young person. She said words to this effect (I may not have the exact wording) "The way I look at it, if I can't figure it out in 15 minutes, it's not worth learning." Some background: we were talking about new presentation tools (e.g. NOT PowerPoint) so her remark was addressed to learning new technological tools. But so interesting. If this were the case for me, I'm afraid I would not know much of anything about the tools I've learned to use.

Her expectations are quite high, both for the tools (they should be entirely intuitive) and for herself (I should get this quickly). Not sure how I think about this. Maybe it's just a natural outgrowth of her expected level of comfort with technology, or maybe her constant technological experience leads her to believe that things should come fast and easily.

So where does intellectual persistence enter into this? Is it important? Should we be concerned about this attitude? Does it apply only in the realm of trying to master new tools, or is it just as prevalent when trying to grasp new concepts or ideas? This might involve me for days to come.
