Less is more when it comes to functionality.
Try not to decorate surfaces that you use daily such as your kitchen island.
Have a house rule that does not allow anyone to throw bags, keys, homework, laptops or whatever else onto the island ... because you will just have to keep clearing the items off to use the space - and whatever you clear off will clutter up another space so encourage the people you live with to not use the kitchen island as a dumping ground.
Learn to embrace the look of an empty countertop. The kitchen island is the hub of your kitchen where food is prepared and served. Apply this rule also to your kitchen table and coffee tables.
Similarly, resist the urge to over-decorate furniture. I love the aesthetic of a good scattering of cushions on the sofa, but if the children keep tossing them on the floor it’s probably best to do some cushion culling.
Ultimately you want your home to work for you to the get the most out of it functionally you need to make every space as accessible as possible.
A good place to start is decluttering!
