A practical guide to mindfulness to learn to enjoy without fear of life and make it a great experience. "Mindfulness" is a word that has become fashionable lately, although in fact it is a practice that, implicitly or explicitly, has been used for some time in areas as apparently distant as academic medicine or some religions. Mindfulness, which is increasingly present in the clinical setting, can help us to improve our physical and emotional health. It is a tool with which we can become stronger, less vulnerable and more aware of ourselves and our emotions; a tool that will give us more security and allow us to live without fear and with greater plenitude the here and now, something essential to feel better and enjoy the present.
