Take care of your appearance. It plays a vital role when it comes to impressing a boy.
2. Pay attention to your hygiene.
3. Have a smile on your face. You don't need to be too serious. Boys usually don't dare to talk if you keep looking too serious all the time. So keep smiling.
4. Make eye contact because this is the best way to let the boy know you are interested in him.
5. Talk politely to him and keep him interested in you.
