Is this too much or not bad? I plan to keep my recovery keys in four separate locations, a brand new flash memory from Huawei, a brand new WD External hard drive, my book with a strong cover and my wardrobe, in my wardrobe you can't easily see it because its always dark in there, I use my torchlight to carve those words in there and its even written on the top inside the wardrobe, I tend to keep it this way for now till I can get a Nano X.
Using too many place is also not advisable. Too many copy means too many chance to expose your privet key to others. Better use a digital device and write it down to a steal plate as the last backup. If you are using a digital devices then make sure you won't connect it with your laptop when the internet connection in on.
Using hardware wallet instead of a digital device like flash drive is more preferable but not everyone can afford it so use the best option for you in your budget.
