- Get a book about speed reading. It should cover both techniques for reading the words faster, and for using the structure of the book to retain more during each pass. Do the exercises in the book.
- Pick stuff that has a high signal/noise ratio. That way, the limiting factor will be your brain's ability to process the content, rather than your raw reading speed.
- Only read high-quality books. Spend time reading reviews on Amazon for each book before you start, to ensure that it's a book that you will find useful/entertaining at this particular time in your life.
- Prioritise what you want to learn.
- In fiction books, go faster through parts which cover familiar ground. Sure, there might be some unique perspective that you miss occasionally, but you'll more than make up for the loss with the time you get to spend on new stuff.
