Dear Su Hai, I have a problem and I don't know how to deal with it. I have two elder sisters. They're both clever and always do everything well. I feel I can never be as good as them. I am worried about the following problems these days. Can you give me some help? ◆Should I just be myself or make a change? ◆How can I let my parents feel proud of me? ◆Can you share one of your experiences with me? Best wishes, David
