I prefer to practice it in the morning. First, is because we all wake up and start our day in the morning that we must do it first to be less stressed and more calm and to affront all the obstacles during the day
I prefer to do it before bed but I've been so tired that I do it in the morning. Working on that. My real preference is doingit all the time. I carry a small journal with me that I refer to as My Book Of Gratitude. Throughout the day as I feel gratitude, I write it down. No matter how small. Anything that made me smile or feel joy to have it or experience it.
