Practice meditation for eleven minutes in a coffee house. Put on a timer. Focus on being present to your body, breath, and ambient sounds. Letting go of fleeting thoughts as they arise. Be here: on the spot. Sometimes it's helpful to gaze at your hands on the table holding a book. You want to look normal within a social environment - not calling attention to what you're really doing. Notice when you slip away into "elsewhere". Return. Do this practice until the eleven minutes are up. You'll find this practice carries over into your everyday life. You become more present to your life moment to moment.
