The statement above reminds us that being attentive costs something. To fully listen and be aware requires some level of deliberate focus. Given stimuli that constantly try to grab our attention, it’s kind of hard to do that.
Bringing awareness to the moment is crucial because it brings awareness of what you are feeling at the moment. As simple as it sounds, it’s actually really important because your mood determines the quality of your actions. Feeling really motivated and energized? Do the hardest and most important task on your list. Feeling scatterbrained and under the weather? Do simple and menial tasks instead.
Aside from self-awareness, mindfulness also helps with appreciating the moment. Worries about the past or the future are irrelevant because the present is only what is. That understanding brings peace of a mind and encourages just being with it.
