You learn no skill or knowledge in one go. Mastery is only possible through repetition.
To learn, retrieve, and challenge yourself.

What you read evaporates.
One moment you picture yourself applying all the useful ideas from a book—next, it's like you've never read it.
What's going on?
Memory runs on emotions.
When something resonates, it's likely to stay with you. But with so many useful ideas, remembering them is hard.
You need a system.
Jog your memory often.
Most people reread, but it doesn't work—it's passive and only creates an illusion of knowing.
The best way to remember is to retrieve knowledge repeatedly and think of ways to apply it in your life.
Test yourself. Bonus points if you space out your practice.
School made us hate tests, but they're a valuable learning tool. What you retrieve from memory will stick with you longer, and you'll be able to apply the knowledge in more situations.
Output over input. Flashcards over rereading.
This sounds like a lot of work. It is. Luckily, not everything needs to be committed to memory. Whatever you can look up, you can save. In a note-taking app, for example.
How to decide what knowledge to remember?
Whatever knowledge you need spontaneously should become part of you. You can't speak a language by looking up every word in a dictionary—you need to acquire it. But facts you can look up? Leave it to your note-taking system.
My frictionless system to feed my first and second brain is a tool called @readwiseio.
I turn everything I want to ingrain into a flashcard; everything else goes to my second brain—@RoamResearch.
Regardless of where your knowledge lives, you need to review and apply knowledge to learn. Without action after reading, your effort is wasted.
Be kind to your future self. Quiz yourself to transformation.

Build a learning infrastructure if you want to be effective.
Your mental bandwidth is limited, and your mind is like a sieve—only part of what passes through sticks.
To stop forgetting, you need a second brain and feed it.

Your mind is a sieve.
Only a fraction of what travels over your neural pathways sticks; everything else is filtered out.
Forgetting is not a curse.
Without forgetting, everything that you ever did or said would haunt you forever. But if you're trying to learn, you want to minimize forgetting in the long term.
Become a professional learner to stay relevant in your job.
On day 1 of #Ship30for30, I make a case to look at your work through the lens of learning. In an increasingly complex world, that's the only way to thrive.

How are you going to stay relevant in your job?
In our fast-moving world, simple and complicated problems are evaporating and replaced by complex ones. Never did companies and institutions have to solve so many challenges in so little time.
You have two options in this new reality: innovate or die.
Change has killed the knowledge worker. Knowing is no longer needed—everyone has thousands of encyclopedias in their pocket. What's needed are new insights. But insights are lacking as workers still rely on old systems.
An excellent opportunity to write my personal manifesto for why I write daily. It's always good to come up with excuses if it helps healthy habits develop.

Writing is thinking.
Without scribbling or typing, I have few coherent thoughts. But when I focus my mind on explaining something using text, a rich mental landscape comes to life.
I've been a writer for as long as I can remember.
When I got my first PC at age six, the first program I wanted to use was the text editor. After all, I just learned to write and had stories to tell!
