Jocko Willink is insane. (http://jockopodcast.com/)
He is one of the guys who says something you're just like: "yup, makes sense".
He has this immense aura, confidence and willpower paired with humility/vulnerability , so that at least I put a high value on his words.
He is also a no bullshitter. You want to do something? Start now!
Want to be nicer? Be nice right now.
Want to get stronger? Do sports asap and eat appropriately with your next meal.
Want to foster your bond with family and closed ones? Call them right now.
Don't put it off. Do it now!
I for one worked through the night and finished my to do's. Then caught a flight to Amsterdam, waiting for my friends to arrive right now and will follow through on being more present and not worried about outstanding work.
