We may think of joy as something that happens spontaneously. Few people realise that it needs to be cultivated and practised in order to grow. Mindfulness is the continuous practice of deeply touching every moment of daily life. To be mindful is to be truly present with your body and your mind, to bring harmony to your intentions and actions, and to be in harmony with those around you. We don't need to make a separate time for this outside of our daily activities. We can practise mindfulness in every moment of the day as we walk from one place to another. When we walk through a door, we know that we're going through a door. Our minds are with our actions.
Haven't noticed Trump being particularly joyful.
