Add books that complement the skill. Computer programming books you might add web site design or a book on how things work or some prewritten codes
For learning to drive, you might add relaxation book, methods to learning, mechanical repair manual, books on motor racing.
One other method if you cannot find more books, search the web - photoreading different ways of having the same thing explained is quite interesting - afterall who says that direct learning is limited to books
