One set of dry clothes for evening. Dry sleeping bag. Protect These. Keep them in separate bags to everything else and separate from each other so you have at least one dry even in a accident. As soon as you pitch up take off boots to air feet.
Outer pitch tent. Take a sponge dish cloth in the tent for wiping down minimise water that is now inside after you had to break camp in the morning when it was pissing it down. Choose a good site out of strong wind if possible but mainly as dry under as possible as you don’t want water to sleep in and get sleeping bag wet.
Wear wool for day time, topped off with waterproofs that even if they end up soaked keep the wind off. Putting it on wet in the morning isn’t pleasant but you soon warm up.
Drink tea with sugar to warm up quick. The process of making tea also acts to focus.
