Good habits take time to form. Try your best but don't beat yourself up if you haven't met your ideal standards. 

In that being said, I think it's easier to stay tidy when you have less stuff. Here's a nice heuristic to determine whether to keep object X: if X gets stained by dog poop, would I wash it or throw it away? If the answer is to throw it away, you don't need it 🤣
