Actually finishing household jobs in 1 go - ie folding the dry washing, taking it upstairs and putting it away straight away, same with dishwasher, laundry etc
Clean laundry I fold by people and clothes type ie all T-shirts together, all underwear etc, makes putting it away really easy
I have two baskets of cleaning products - one in the utility for the downstairs and one in my laundry cupboard for upstairs bathrooms etc which saves going up and down to get whatever you’ve inevitably left somewhere else - have a 3 storey house, so this is key as the stairs are a bastard!
Making enough food (esp veg like cauliflower cheese, sautéed veg etc) for at least 3 days in the week. I wfh so having food already made in the fridge is excellent to try and cut down eating snacks
Everything has a place; I go round every 4-6 weeks and throw out old papers, shred paid bills / paperwork, and go through DS room and his mountain of discarded old paper, pictures,magazines etc
