If you want to make your world a brighter, happier place, all you need to do are two things: 1) smile and 2) get to know the people you meet on a regular basis—the people who work at the grocery store, the bank, the post office, the restaurants you frequent, and so forth. You do this by showing a genuine interest in them—asking them questions and learning what’s going on in their lives. If you do this on a consistent basis, you’ll soon notice that these people smile when they see you coming their way, they cheerfully greet you, they learn your name, and treat you like you’re someone special. Let me tell you from personal experience, this will brighten your day and make you feel great. This is so much better than the indifference you’ll experience if you don’t smile, and you say nothing. The lesson here is that your world is what you make it.
