Presence brings peace

If you are working on something and you are constantly distracted with something else, you will still have nagging doubts as to whether you missed something in the work you're doing. You will have to check and double check to make sure you did what you set out to do. Even after all this you will still feel that you were not as productive as you could be. You will still feel that you and your work is inferior to someone's who is focused when even though that feeling may or may not be true.

Now contrast that working with presence. Instead of feeling you're missing something, since you're fully focused on the work you're doing and you have already taken everything into account, you feel more confident of your work. Since you're fully present with your work you have considered everything without rushing, there is no need to check it multiple times. To top it all you know that you were as productive as you could be and that there is no anxiety as to whether a focused person could have done it faster or better, because - you have been focused. 

This my friends is why presence brings peace
