Each time you read a book, listen to your favorite podcast or hear a smart person say something:
1. Write it down (Here)
Something that caught your attention, piqued your curiosity or, at the very least, you noticed
2. Detail how you will apply this thing in your life (There)
How might you implement it at work or in your personal life? Imagine your future self doing it and the outcome it generates
3. Write down the underlying principle or insight that makes this bit of knowledge so effective and universal (Everywhere)
This is its underlying principle absent context.
