请认真阅读下面短文，并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。 注意： 每个空格只填1个单词。 Being yourself refers to not trying to copy anyone or do what isn’t your nature. Then what does it take to be yourself？First, you must know yourself inside. Looking inside is the key to knowing your positive aspects. If you yourself aren’t clear about who “YOU” are and what your personal analysis is, you’ll come to a dead end. It’s essential to be comfortable with yourself and think positively. Once you’ve done a self analysis, it’s time to focus on this material world. Think about what you basically want to do and achieve in life. Make it clear to yourself what you like and do not like and what your passion (激情) is in your life. If you dislike something, don’t try to like it just because your best friend is fond of it. Focusing on your passion and interests will keep you positive. Honesty is the best policy for being yourself. Be honest and express what you feel but make sure that you do not hurt others. Wherever you can speak out freely without holding anything back, it is best to be honest. That adds character to your personality and is essential for being yourself in a relationship as well. Be confident but don’t be overconfident. You have to believe in what you do and what you want. If you hesitate, getting up and giving it your best shot with full confidence is what matters. Moreover, you should have faith in yourself. If you know who you are, it would not matter much what the whole world thinks of you. But that won’t mean that you have unrealistic expectations from yourself. Understanding how to be yourself does not at all mean that you focus only on your inner self. I mean that your external (外在的) appearance also matters a lot. If you are poorly dressed or wearing your dad’s old T-shirt, no one would come and talk to you. So one needs to dress well and look good. Unless people come and talk to you, they would not know what kind of person you are. In a word, you need to have a combination of inner beauty and a smart appearance.
