Living in the now means fully appreciating and savoring the moment. For example, if you are taking a walk, look closely at the plants and flowers you pass; feel their soft leaves, inhale their gentle aroma and look at the subtle tones of color. Feel the soft gentle breeze against your face. Involve all of your senses.
If you are sitting at your desk with a drink, inhale the rich aroma of your coffee, feel the smooth hot liquid in your mouth, feel the shiny smooth keys on your keyboard as you type.
Every so often, make a habit of living in the Now.
