Organize a group to explore a shared area of interest. Book clubs might gather to discuss a new book each month, while a philosophy group might explore theoretical constructs. Current events groups are great for generating discussion. Grab the headlines from either the local or national newspaper, and debate the issues of the day. Whatever your interest, gather in the common room or find a local library or bookstore to host your gathering.
Tip: This can be done virtually as well, set up a recurring zoom meeting and plan a calendar of topics.
