Thank goodness for mindfulness, because during that 30 minutes, there is no time pressure. There maybe before and after, but during you have a free pass to just, well, not 'do' anything except walk and breathe and take in your surroundings. And that's why it's good to do it every day no matter how busy the rest of the day is.
There is always time for mindfulness.
You know by now where to connect with me. Namaste.
