Determining a "home" for every item is the most fundamental aspect of organizing. A specific place where you and your loved ones can always find it and easily put it away. Just to let you know, an item's home may not be where you would typically find such an item. For example, face serums are typically stored in the bathroom. But in my case, it is stored on the coffee table because that is where it is used. Take vitamins for another example. If you take them in the kitchen they need to be stored somewhere in the kitchen, where they are easily accessible since they are taken daily. Mastering this key to organizing will help your space function at its best!
