The top 3 lessons I took from the book:

1. Presence is Charisma.
The more present you are in a given moment, the more charismatic you will be.

2. Whenever you want to be present in a given moment, focus on your toes.
If you are thinking about something in the future or past, snap yourself to get back to present by concentrating on the movement of your toes.

3. A good email is not one when you can't add anything more, but when you can't remove anything more.
