We all love to choose. Sometimes we go shopping for hours, we love flipping through catalogs and with pleasure we linger on the pages of one or another online store. Comparing our needs with the proposals, trying each of them to our reality, we, without jokes, feel a bit like architects, designers, stylists and even engineers. Here it is the recipe for simple human happiness - give us a choice of components, and we ourselves will build from them what suits us best.
