With whatever you are doing today practice a moment of awareness. Clear your mind of the usual chatter. Really try to get rid of the worry thoughts and the to do list. Now, feel your butt in the chair. Or your feet on the ground. Take a deep breath and just notice anything you can pick up with your feeling senses. Temperature, pressure, pain or tightness, heaviness or lightness. What do your feeling senses notice, without judging or analyzing, continue noticing. Thought will creep in, and all you have to do is clear your mind and ground yourself low into your belly. Feel again.
Being awake and aware in your moments gives you a choice to respond to what is true and now. To respond with your inner ninja, instead of your outer multitasking, over thinking and worrying self.
Practice.
