It’s your life and you should choose what to do with it. It’s ok to take advice or views from your friends, but you shouldn’t let them make your life decisions. If you feel pressured, tell that person that you don’t want to do that certain thing with them, or ever. You should always speak up if you have a problem with something, even if it makes you look different or weird; people will respect you for your courage. If they don’t, then they weren’t meant to be in your life. The people that respect your opinions and decisions are meant to stay in your life forever life.
And if people think you are a square or a narc for having you own opinion and mind, then be the best square you can be.
Leaders make their own decisions, and followers follow what everyone else is doing.
