The C21NLP is the best app I’ve ever downloaded. David Shephard has the gift of turning complex subjects into a pleasurable and joyful experience. The app is so versatile that you can create your own playlist of your favourite subjects. Mine is the Daily Power Rituals. I listen to it every morning and before I go to bed. The language is so well crafted that it is “as second nature to me now, like breathing out and breathing in…” I highly recommend daily dosages of C21NLP.
