Mindfulness is everywhere. It refers to the skill of being able to notice what is going on in your mind and body, in the moment, without getting too caught up in it. The game changing proposition is that by practicing mindfulness, you may be able to respond to situations more calmly and with clarity, rather than reacting to situations in ways that make things worse. Think about it, if you don't get highjacked by the stories you tell yourself or by overwhelming emotions you feel, you may be less likely to lose your temper, and more likely to handle difficult situations with confidence and grace. Another upside is that you will be more present and capable of enjoying life as it unfolds, moment by moment.
Mindfulness practices build emotional and social intelligence, mental assets that matter significantly in how one navigates life. But it's one of those practices that needs to be experienced to fully understand how it might impact your life.
If there is a mindfulness skeptic in you, perhaps the raw science behind mindfulness will allow you to be more open to it. More to come on that!
