Learn to read faster. I used to lose focus, and realized my reading speed wasn’t keeping up with my processing speed. The slow pace made me bored and frustrated.

To read faster: I’m no expert, but what works for me is basically scanning chunks of words with my eyes, and moving quickly across the lines — while trusting that my brain is processing what it’s seeing. I actually retain more of the information this way, surprisingly. Experts can chime in with more detail, but this has worked for me.
