Before you dive in, figure out what your decluttering goal is. Do you merely want to get rid of visible mess, or do you want to create entirely new household organizational systems to use going forward? Knowing what your end goal is can help you prioritize tasks and figure out your next steps.
Another trick to kickstart your decluttering? Start with what you feel is the easiest room first. For example, if you know you need to do an overhaul of your entire wardrobe, don’t tackle your bedroom and closet first. If you begin with a simpler decluttering job — say, cleaning out and reorganizing your spice rack — it can empower and motivate you to tackle bigger decluttering projects.
