If your kitchen and living room are attached (or you spend a lot of time in the kitchen), get a dehumidifier. Stops the room from filling with steam when you are boiling stuff. The plastic ones with the beads are fine so long as there's no pre-existing damp issues

Also, have things around that make you happy. No one is going to judge you for having an old Teddy on your bed or for wearing superhero pyjamas

Know where your gas and water shut off is. Have contents insurance. If you have a car, know who can give you a jump start (or have one of the battery packs for jump starting)
