Mindfulness is present moment awareness; non-judgmental awareness. If you practice it every day, and experiment with non-judgmental awareness of body and mind, and if you cultivate curiosity, you may enrich and enjoy your experiences more. In fact, mindfulness is one of the factors in cultivating joy.

I think that, like many people, when I first came into practice, I came into it for myself — to lessen the suffering/dissatisfaction that the Buddha described in the First Noble Truth.
