I currently live with my parents. If I moved to a part of the country with lower cost of living (which I could feasibly do since I have a remote job) I could definitely afford to rent an apartment or even buy a condo by myself, but I know from previous experience that I don’t enjoy living alone and would probably get depressed.
I've never lived alone and at this point I'm not sure I even could.
I've had roommates all through college and into my early career. Went from a year back home to rooming with an old high school friend. I moved in with my now-wife six months after we met, because she had started law school and couldn't afford to live alone. She was the fourth of five roommates living together before we started going our separate ways. The first was the best man at our eventual wedding.
Having roommates just feels good. I love living with other people. I love the constant opportunity to socialize. I love cooking big meals for a bunch of close friends, going to the gym together, planning vacations together, hostimg big parties with neighbors and other friends.
If you can find people you get along with, it would be crazy not to live with them.
