Hurray, travelsafar, we all need to ask ourself those questions! The world can't afford the current emphasis on 'new' and what is the latest fashion. One positive aspect of the pandemic is that it may concentrate our thoughts on what really matters in life.
Please don't throw out anything just for the sake of it. Resources are scarce and precious. And you loved it once. You wouldn't change your partner or your pet because they don't look like the latest film star or the fashionable breed of dog or cat!
Maybe add one or two new contrasting towels in the bathroom, but keep the present ones for a change again, later. A bright new cushion or two may be fine, but not a new sofa! A lift to the spirit by changing something can be great, but perhaps move things round rather than replacing them.
Perhaps you could do a swap with a friend or family member who is fancying a change of scenery, too? If you do indulge in the impulse to change, the charity shops or recycling centre would be pleased to have what you are tired of.
