The poet and doctor William Carlos Williams used to carry a notepad around with him in which he listed "Things I noticed today that I've missed until today." Make his practice into an ongoing project in your home or group. Every morning, remind yourself that during the day you are going to notice something new or see a familiar sight in a new way. That evening, describe your discovery to family or friends. If you are doing this project as a group, allow time for reporting at your meetings.
Make a visual record of your expanding awareness of the world. Once a week, perhaps on your sabbath, find or draw something to represent one of your observations and paste it on a wall calendar. Over time you will find yourself becoming more attentive as you gather material to include.
