"I wish I had straight hair." "I'd like to be taller." Sometimes, we may want to look a bit more like someone else. However, the pictures we see on TV and social media can give us improper ideas about how our bodies "should" look. The truth is that everybody is different—and that's a good thing. Accepting and feeling good about our bodies is really important for our self-confidence (自信).
If you feel positively (积极地) about your body, you are more likely to take care of it well. Research has even shown that you are more likely to take part in activities and perform well in school. However, feeling worried about your body could make you step back, do less well at school and even feel down. The cost of trying to achieve the "perfect" look is high. If you are spending a lot of time on it, you will have less time to spend with friends and to make important memories.
It's important to remember that everybody is different. To develop a positive body image (形象), you should try to talk positively about your own body and other people's bodies. Try not to pay too much attention to your look. Instead, think about what your body does for you. And you also should treat your body well by eating different kinds of food, doing sports and getting plenty of sleep. Remember that you are more than how you look.
