The natural, and easiest, way to make good friends is to spend a lot of time with people. Some of those people will become good friends with no effort at all.

Given nuclear families etc. in the West, this is kinda hard as an adult. Happens automatically as a child and college student, though. My advice to you is:

1) Get a housemate or several. Better yet, join an already shared house. Forget about your preconceptions about whether you "can" live with other people or not. You aren't special, people lived together for ever.

2) Explicitly decide to work through this "doesn't feel natural to me" thing. OK, fine, it's gonna feel kind of awkward at first. By the 5th friend-hunt it won't.
