You should have put books last on your declutter.

A way to declutter is to either install a Little Free Library, donate them to your neighbor's Little Free Library or your library. Donated books to your public library will be used for their book sale. The proceeds go for programming or much needed materials that are not covered by the overall budget.

Forget fast fashion. Invest in quality items. Think style not fashion. Why do you think the preppy look has endured? Timeless style. The clothes are made from top notch materials and in some families are passed down.To do this you must familiarize yourself with what makes clothes high quality. I shop at estate sales or thrift stores. Recently, I scored several Brooks Brothers silk/cashmere shell and cardigans. A timeless design.

I did not have children, so I can't speak on buying the best for children. Though looking at trends for children, look to the Scandinavians and their simple designs. There are children consignment shops. Rent some toys.
