What’s the best time of day to practice?
Anytime that you can get yourself to do it is the best time! It doesn’t really matter when; just do it!
What matters is that you practice regularly, so you have a chance to develop your skills and to see if the practice helps you experience positive change in your life.
Many students find if they don’t do it in the morning, they never find time the rest of the day. Some students like to do it right before bedtime because it helps them quiet their minds as they prepare for sleep. Still, others find a break in the middle of the day works best.
Be willing to experiment a little. Pick a time to do your ten minutes of mindfulness practice, and if after a few days you find that’s not working well for you, then see if there’s another time that would work better. Keep at it, until you develop a regular, daily routine.
