The traditional paradigm of learning is skills development. However, the emerging approach is state development. Let’s not throw the baby out with the bathwater. Skills are important, but their impact has a direct correlation with your state of being. Well-being and being well. Heart, mind and spirit.
For example, picture yourself as a skilled presenter who is also enjoying the birth of a new born child. In your sleep derived stupor the potential impact with your audience may well be limited.
