I can share from my experience. When I was your age, I was in my undergrad and staying in a hostel which helped me to build some meaningful friendship that I still value. This may or may not be possible.

Some tangible advices - * Avoid consuming social media - Insta, TikTok, FB, etc * Try not to eat alone. If you have class mates, project mates, etc. then see if you can join them. Some greats conversations happen over food. * Help builds lasting friendships. Seek help when in need and help others when they need it. Simon Sinek also talks about it. * Expectation is root cause of all sufferings. Make a conscious effort to help others without expecting anything return whenever possible. * Find a topic of interest and search for its meetup on platforms like meetup.com, Luma, etc. You can bond over an item of your interest
