How should I organize my notes to actually remember what I learn?

I've watched people fill notebooks with beautiful handwriting that they never touch again. The real question isn't organization—it's connection. Patanjali teaches that learning happens through practice, not collection. Your notes should mirror how your mind actually works, not some ideal system. Some people need visual maps. Others need to write the same idea three different ways before it sticks. What matters is returning to your notes with intention. I'd suggest organizing around *themes* rather than dates—group what connects conceptually. Then, crucially, review what you've written. Not to memorize, but to see where your thinking has shifted. The best note-taking system is the one you'll actually use and revisit. Start simple: date, idea, and one sentence about why it mattered to you that day. Notice what naturally clusters together over time. That's your real structure emerging.
