I often see people with their shoulders up, taking fast and exuding the feeling that there is not enough hours in the day for all they have to do. Their pace is hypnotic and their habit of rushing through life can be hard to break.
Do this very moment justice. What are your eyes, ears and other senses telling you about where you are right now? Are you aware of your breath? Are you really noticing how you speak and what you say? Life is not meant to be lived in constant stress.
Focus on the present moment. A feeling of contentment arises from acknowledging oneself. In a day, anything can be accomplished perfectly just by pacing oneself to accomplish only what can be should be done in a day.
