Don't sweat the small stuff- in the grand scheme of things, it won't really matter. It just leaves you feeling horrid, and for those unfortunate enough to catch you in that state, they will remember you as angry and mean. Not a nice way to be remembered.
It's okay for your home to look lived in. A bit of mess never hurt anyone, especially if it meant you got to spend more time doing stuff with your family. Children in particular probably won't care if their home had been a show home, but they will care if they felt like they missed out on quality time with you. Show them you love them by watching them, and taking an active interest in who they are and what they like.
No use crying over spilt milk. If you made a mistake, attempt to fix it/apologise for it then get over it. We are all of us fallible. We will make mistakes, but as long as we try to avoid them as best we can, try to atone for them, learn and grow from them and move on, then it really is okay. And obsessing over them wont help. It just becomes a consuming self-destructive attitude which has the potential to be dangerous.
Random much? Sure is. But that's some of what's going on in my mind right now...
