Some actions are not melakhah at all, yet do not belong on Shabbat: business, planning work, strenuous effort. Learn the basis of "pursuing your affairs" and its limits.
The Gemara (Shabbat קי״ג ע״א (113a)–ק״נ ע״א (150a)) expounds Isaiah 58: "from pursuing your affairs" - your affairs are forbidden, Heaven's affairs permitted; "and speaking words" - weekday speech; "and honor it by not doing your ways" - weekday walking and dress.
One may discuss charity, matchmaking, and teaching a child Torah or a trade (Shabbat ק״נ ע״א (150a)) - since these are mitzvah needs.
Shabbat is not only "not working" - it is a change of pace, speech and awareness.
List 5 typical table topics and sort: affairs of Heaven or your affairs.
One who changes speech too experiences a complete Shabbat.
Test yourself before marking the lesson complete.
