Your relationship
Both of you may have your own ideas and find reassurance in something that lasts. The person wanting a new direction and the one wanting to preserve the form may take different-sized steps toward change.
As romantic partners
Discussing a habit to change separately from reassurance to keep can leave room for one trial, rather than only choosing between immediate change and preserving everything.
As friends
Even if you enjoy a familiar restaurant, a brief visit somewhere new can bring a different view without leaving comfort entirely behind.
As colleagues
Agreeing first on the reason to change and the steps to retain can help a person eager to proceed and a more careful person choose the same trial scope.
