Practice Being Present
If you are trying to develop a habit of being more mindful in your life, it can be helpful to engage in some regular activities that promote mindfulness and teach you how to pay attention in this particular way to your present.
Mindfulness exercises are meant to help you practice being engaged in the moment. Take these and customize them to fit your life and needs. Use them as inspiration to find what works best for you. And pick only those that make sense and feel right for you.
