another huge piece of advice: separate out 'tidying', 'cleaning' and 'organising' in your head. they're not the same thing and a lot of paralysis and overload comes from either misidentifying what your space needs, or trying to do all of them at once with conflicting goals.
TIDYING means clearing space, making your environment orderly and inviting. it usually entails removing clutter from surfaces, clearing the floor so you can move around easily, and creating psychological ease by putting everything visibly in its place. It's very visual, and can also involve things like straightening picture frames, squaring pillows, folding blankets on the couch, etc. It reduces chaos and noise and makes a space comfortable.
ORGANISING means sifting through belongings, ensuring that what doesn't need to be kept is thrown out and what does need to be kept is kept well. This often means categorising by room and function – teaspoons go in the teaspoon drawer, and the teaspoon drawer stays in the kitchen. It can also mean indexing things so you can find them easily (markers sorted by colour, paperwork divided into topical folders, books alphabetised) and preserving things (moving photos out of direct sunlight, keeping open flour in a sealed container, sleeving trading cards).
CLEANING means removing built up dirt, dust and grime, reducing the level of environmental contaminants and making your space sanitary. Bacteria are a fact of life, they love to hang out in dust and cling to pet hair and multiply on any given surface. Cleaning is how you keep that stuff in check, preventing it from building up to the point it affects your health. This means wiping frequently touched surfaces with disinfectant, sanitising utensils (doing the dishes), washing bedding and clothes (and yourself), and sweeping/vacuuming and taking out the trash to physically remove dirt from your home.
Tidying is not the same thing as organising – shove the mail, bills, dirty teaspoons and your gardening gloves in a drawer, and you've tidied the table. Sort the paperwork into piles by deadline, put the teaspoons in a cup, and roll the gloves together so they don't get separated, and the table is untidy but organised.
Similarly, a tidy or organised space can still be filthy. Just because all the yellowed newspapers and trash bags are sorted by date in the basement, out of sight, doesn't mean they're clean. A chaotic, cluttered space can still be very sanitary if it's being kept clear of refuse, and wiped and dusted often.
Sometimes tidying makes your space less organised, and vice versa. Organising often shakes out a lot of dust and makes the space dirtier. The classic "it's even worse than when I started" feeling is often the result of going into a room with the intent of tidying, then actually starting the task of organising instead. It's a lot easier to tidy an organised space, and organising first is usually the right instinct, but the distinction isn't intuitive so the sudden cluttering effect can be really demoralising. Remember they're three different things with different goals. Sometimes they overlap, but sometimes they conflict. That doesn't mean you're doing it wrong.
