To be mindful is to be fully present with whatever we are doing. If you are drinking tea, just drink your tea. Do not drink your worries, your projects, your regrets. When you hold your cup, you may like to breathe in, to bring your mind back to your body, stop your thinking, and become fully present. In that moment, you become real and the cup of tea becomes real. In this state of true presence and freedom you enjoy simply drinking your tea.
