To make new friends you should start by joining groups or clubs with similar interests to you. Put yourself out there and be friendly to those you meet so they know you're open to being their friend. Keep conversation polite, but be you. Don't pretend to be someone you're not. If things go well, you can ask them for a way you can contact them to hang out or chat again. Continue to be nice and chat with them regularly to keep your friendship thriving.
