Assuming you would like tips on how to come across as cool:
It can be difficult to seem cool, especially if you don’t feel particularly comfortable in your own skin. However, there are a few things you can do to give off a more aloof and collected persona.
For one, try not to care too much about what other people think of you. This will make you seem more confident and self-assured. Secondly, focus on honing your own personal style. Be fashionable but also be sure to wear something that makes you feel good – something that expresses your unique personality. Finally, be yourself! The most important thing is that you stay true to who you are, no matter what anyone else might think.
