Mazel Tov Syag for the bar mitzvah.
If you don’t believe in spring cleaning then don’t. And don’t let other people’s comments rattle you. I love doing spring cleaning before Pesach, otherwise it doesn’t get done. After pesach, I rather spend the afternoon at the park with the kids. And trust me my house needs it…
That doesn’t mean Chametz free. A couple days before pesach I go over every corner with a vacuum cleaner, but because everything was already ‘spring cleaned’ and organized it only takes several hours and then the house is chametz free.
As for your ‘wish list’ I can guarantee that if you had everything on it, you would create a new one, and still have a ‘wish list’ that is life.
