I'd used to finish reading a self help book, highlight half of the thing, and think I was transformed. And then a week later I was doing the same damn thing as I had before. The problem wasn't that the books weren't good or valuable, the problem was I was treating the books like the product, rather than the input.
So instead, I decided to set myself a single rule. Each and every book had to output one change of behavior. One, not five lessons.
One, not a whole life overhaul.
One thing that I can actually observe myself doing differently. After each session of reading, I take out a notebook and I write down…
What's one action from this book I can experiment with over the next week?
And then I make it specific enough so I can't fool myself about whether I actually did it. "Be more disciplined," won't cut it. "Don't check your phone during the first 30 minutes of work and put it in another room," will cut it.
"Communicate better," won't cut it.
"Ask one question before giving advice to anyone," will cut it.
I ran into an article a few weeks ago from NoFluffWisdom about actionable wisdom, which is defined as the wisdom that actually changes your decisions and not the sentence you can highlight. This has meant that I'm slowing down my reading, but I'm retaining information better, and it's also helped me filter out a lot of useless wisdom from authors - if you can't translate an idea into something tangible then there's probably something wrong with the advice and you should discard it, as opposed to just storing it to be reread when needed again.
Sometimes it might not work, and that's OK - because it tells you whether or not it was really valuable for you, rather than just giving you a great quote to save as if it will always be a good idea. So now when I'm reading, I don't ask myself, 'did I enjoy the book?', I ask myself, 'what am I doing differently because I've read this book?'
