I like the small pleasures of hiking a lot.
When on the trail I'm in the habit of carrying a small container of 'dry shower' and use it to ease any discomfort on my feet. I find that it works well for me, especially when they are feeling really hot.
I also carry a small Lifeventure shower head and a basic lightweight water container, (up to 1L) and if I've been walking for a few hours, especially when it's really hot and if there's no one around, I sometimes just strip off, hang the container from a tree and have a quick cold shower.
I always keep my tent footprint (or groundsheet) on the outside of my rucksack, really useful when I want to take an afternoons sleep. I sometimes get to the point where the desire to sleep overwhelms me and I need an 'instant bed.' Hat over my face, rucksack as my pillow, shoes and socks off, wiggling my toes, brilliant!
When I can, if passing a shop, I will often buy a tin of Ambrosia creamed rice. I carry it until I can wait no longer then I eat the lot slowly! Always seems to taste the best for me when I've achieved a personal goal, e.g. sitting on the top of a mountain on a nice clear sunny day, relaxing and looking at the scenery. I try to make each mouthful last as long as I can to enjoy the maximum taste.
