I do a lot of reading. I hate reading. However, I enjoy learning.

Sometimes reading is the best way to learn.

Sometimes re-reading is even better. Do this slowly.

Sometimes reading lots of different sources about the same topic is the best. Do this quickly.

Other times, I learn by listening. Or watching. Or trying. And more often than not, by failing.

Like anything else: Speed reading is a tool. Use it appropriately.
