1. Do it now. Procrastination leads to getting snowed under a pile of work.
2. Use your trash can liberally. Born organized people dont think twice about throwing things away. They arent tempted to keep old worn out appliances around just in case. They dont worry about whether they can recycle that mayonnaise jar or not. They just toss things.
3. Get into a routine. B.O.s dont wait for time to clean the whole bathroom. They wipe off the sink every time they notice its splashed. They shine the mirror every day while brushing their teeth. They run sudsy water to use while cooking, so stirring spoons and saute pans are washed before the meal even goes on the table.
