If you could do something that would make people happy, and it would cost you neither money nor time, would you do it? If that same thing made you happy, would you do it? What is this magical thing that will brighten your day and the days of people around you and yet cost you nothing? A smile.
David NivenMany of our feelings of satisfaction or dissatisfaction have their roots in how we compare ourselves to others. When we compare ourselves to those who have more, we feel bad. When we compare ourselves to those who have less, we feel grateful. Even though the truth is we have exactly the same life either way, our feelings about our life can vary tremendously based on who we compare ourselves with. Compare yourself with those examples that are meaningful but that make you feel comfortable with who you are and what you have.
