Believing the earth wasn't flat rather an oblate ellipsoid or that earth revolves around the sun, not the other way round. If everyone always conformed to their peers we wouldn't ever see any changes in the world.

Peer pressure impacts teenagers to adults. It simply means getting influenced by people who are a part of your social circle. It is critical to understand that in what way peer pressure is affecting you. The important question one should ask:
a: Am I losing control and agency in my own life?
b: Are all of my decisions influenced by someone else's thoughts and ideas?
c. Am I always looking for external validation?
These are not easy questions to answer and at times the wrong that is done to us is not identifiable. Don't force yourself to do things you aren't comfortable doing.

One has to be affirmative about what one wants in life, ethically make a decision and then make a choice. Once the choice is made, you have to stand by it. You need to ask yourself if the next step is important for you or needed by you. It is important to set boundaries, it's not being selfish but rather self-care. Your mental health and wellbeing come before anything else.
Be assertive, keep your points forward.
However, one thing must be kept in mind: The pursuit of being a non-corfmist for the sake of appearing different or a rebel is an unhealthy motivation.
Do something because you feel it is right, not because everyone else is doing it!
