Practicing mindfulness is not necessarily about putting aside time to meditate. It’s about learning to switch on-and-off your ability to live in the moment.
Even if you have 1000 things to do at work, if you’ve set aside one hour to enjoy dinner with your friend, can you forget about work and engage fully with your present company?
That’s what mindfulness is all about.
