Right. One-on-one lessons are the most efficient way to learn things, but not necessarily the most practical, because experts generally don't have infinite patience for stupid questions. If I were Unquestioned Emperor Of The World, I'd learn everything from calling the appropriate expert into my office, but as it is I can only do this sometimes. Still, I'm often amazed by how long I can spend trying to understand something tricky in a book, and how quickly I can get un-confused as soon as I start talking to someone who really understands it.
