If you don't want to be laughed at like this again, just try my advice.

First of all, you should respect yourself, or you will always be looked down upon.

1. Take the initiative to deal with others, take the initiative to talk and chat with others, say whatever you have, don't bow your head, hold your head high and look at others.

2. do exercise. Set aside some time to do some sports every day, especially outdoor sports. Run! You can go to a nearby school and ask some friends or classmates to compete. Whoever loses will treat you to dinner. You can lose, but you can't always be the last one. Take out your momentum and courage and sprint with all your strength. Climb the mountain! Try to go with your friends in the morning, climb to the top of the mountain and have a panoramic view. You don't want to rest after climbing a few steps. Show your perseverance and don't give up easily.

3. Volunteer at weekends to help others. You'll get something.

4. Ability to organize some activities by yourself, such as organizing colleagues, friends and family to travel together, outdoor barbecues and so on.
