I do feel unsatisfied with the level of sharing with the people I currently socialize with. I also often feel lonely, even when I'm with friends. Besides my wife I don't think there is anyone I know who is even interested in building a truly intimate friendship with me. So how do I find my tribe as a 28 year old man? How do I make real intimate friendships? Maybe that is my real obstacle right now.
Ain't that always the question. 1) Volunteer. 2) Go to church. 3) Join a club. 4) Continuing ed. 5) Sports organizations. 6) Hobby organizations. I tell you what - you spend time at a soup kitchen, a unitarian church, the Freemasons, a cooking class, a climbing club and a model airplane flight chapter and you will be anything but solitary. That's different from not feeling isolated - and you should never conflate the two - but you will have had ample opportunities to find and bond. I also recommend having children. You will find yourself forced to spend time with parents you never would associate with otherwise, and you might even enjoy it.
