Decluttering is an antidote to free-floating anxiety. A decluttered home makes for a decluttered mind.
If you're looking for a step-by-step guide, the "KonMari Method" is a delightful approach available in Marie Kondo's international bestseller, "The Life-Changing Magic of Tidying Up." My favourite tip: carefully study all your things. Hold, feel, evaluate each item. Keep only that which "sparks joy." Divest yourself of the rest--but not before thanking each item for its years of faithful service.
Adding joy, fun, and graditude to the equation transforms a chore into an adventure of self-discovery.
