The correct yet disappointing answer is that this isn’t algorithmic. Here are some thoughts though:
- Prioritize quality friendships, not quality friends
- Find the right groups. Easier to find likeminded people through a common interest.
- Be extremely forward. Asymmetric upside on this is insane.
- Stay in contact
I’m also a noob at making friends though.
Later update: realized this was about finding friends, not making them.
