First of all we have to understand that we can be mindful of normal activities at normal speeds. Sometimes people believe that mindfulness can only be possible when we slow down. But when we have a time limit it is very helpful to see that it is an opportunity to do actions and be mindful of actions in a faster way. So perhaps the concept "I have to slow down to be mindful," is causing some of this stress. So if we see, "Oh, this is an opportunity" rather than "This is a pain," we can try to be more mindful in a quicker way. So that we cause ourselves less frustration at that time.
