Your family doesn’t have a pancake Saturday? Start one. Traditions are just habits somebody refused to drop.

STILLNESS
Every tradition was invented by somebody, usually without any ceremony. It became a tradition because one person kept doing it after the novelty wore off, until everyone else started expecting it. Nobody has to grant you permission to begin one.
Pick something small and repeatable, a breakfast, a walk, a card game, and do it three weeks running. By the third time other people will be counting on it, and that is genuinely all a tradition is.
Which tradition could you start and simply refuse to drop?
Free, with nothing to buy inside it.
