Should one follow ones friends that are jumping off a cliff? No right? That answers the question.
Now to the real question, How do you make friends? Everyday, say hi to 10 random people in college. Get the numbers of 5 new people, and decide atleast 2 that you want to stay in touch with. Most people are themselves shy and if you approach them, they will greet you warmly. Small talk like how much the canteen sucks, or how hot the climate is pretty good. With guys, talk about girls, with girls, talk about movies, songs, other girls, studies etc.
Main thing to keep in mind - Dont get involved in other peoples affairs, dont poke your nose. Stay away from group politics. And dont bad mouth anyone no matter how much they deserve it. That should get you a lot of friends.
Dont think, say HI. There was a time when I smiled, said Hi to this chic, and we both just looked at each other, looked around for 5 seconds at each other cause we had nothing to say. And then we started talking about how awkward that was and spoke for half an hour. Just tell you, shit happens, you can even turn it over sometimes. Sometiems people dont even acknowledge your greetings, dont pay them too much thought, ignore them. If you ping them on facebook and they didnt reply three times, unfriend them and move on to people that you like.
So that's just the short version of it. There is also twitter, facebook, linked in, whatsapp, college groups, activities, studies, study groups, Tinder, and if you're gay there are a ton of gay sites (dont ask me how I know that, i'm very straight lol). So yeah, this is an age where making friends is as easy as reaching out, and reaching out consistently.
