Moderator：Hello, ladies and gentlemen. It gives me great pleasure to introduce our speaker for today’s lecture, Dr. David Ford. Dr. Ford, professor of psychology at Stanford University, has written numerous articles about how to be more mentally healthy, in spite of the great stress from work or difficult relationships in the modern society.
        Dr. Ford：Thank you for that introduction. I feel happy to meet you here. Why is it that some people seem to have their life in order, seem to know who they are, seem sure of where they are going, while so many others feel lost and alone in this world? Maybe you are one of those people who feel lost. Maybe you question whether there is any meaning or purpose in life, or just aren’t exactly sure what you are doing with your life. It’s easy to think others have it all figured because of their glossy outer appearance, until you walk a mile in their shoes. Just about everyone feels lost at some point in their lives. It’s inevitable. It does not matter how wealthy or poor you are, life can seem pretty humdrum and pointless sometimes. That’s because nobody is born with an instruction manual for life. We’re all trying to make sense of life as we go along. And just because everyone feels lost sometimes, doesn’t necessarily make it a pleasant experience. The sad thing, though, is that there’s no quick and easy way to figure out your life and fix the feeling of being lost. However, as with many things in life, a little extra understanding and compassion can help you navigate through these negative feelings as if unfazed. People who feel lost in life don’t like themselves very much. They tend to have a distorted sense of self that hinders them from appreciating their own beauty, intelligence and worth. They often don’t accept one simple truth— that who they are is enough. All they seem to see is how inferior, unworthy or insignificant they are, and how nothing they do is good enough. When you see yourself as inferior and feel less than worthy, you’ll be depressed, sad and unhappy. You’ll feel lost. That’s why you need to see yourself in your true perspective. You are special—a valued member of the human family. Just because you are different or unique in some way, doesn’t make you any less valued. Your capacity for love, happiness and success is equal to any other person’s. Spend more time with yourself to figure out who you really are inside, and what makes you happy. Then pursue those things that make you truly excited. You owe it to yourself to be happy. Believe in yourself and your own potential because if you don’t believe in yourself no one else will. Any feeling of insignificance, disconnection, or loneliness is simply illusions because you are nothing but significant, connected, loved and could not be alone if you tried. Be happy for who you are. All your strengths, quirks and imperfections— that’s what makes you special and lovable. Thanks for listening!
