Of all the various races of Middle-Earth, Hobbits get some of the most focus in the Lord of the Rings series. This is understandable, since a Hobbit is the main character of both The Hobbit and Lord of the Rings. Despite their size and relatively relaxed lifestyle, Hobbits still manage to be incredibly important to the fabric of Middle-Earth, and are some of the main characters involved in saving it throughout the story. They become heroes in their own right, stepping outside the expectations of what everyone thought a Hobbit could be.
Of course, these Hobbits that were involved in the main adventures of the story were somewhat exceptional, as most others of their kind wouldn't be as eager to take on adventure. For the most part, Hobbits lived quiet and uneventful lives, which is just how they liked it. Even if they weren't out saving the world from encroaching evil, they still played important roles in their own community and were committed to sticking to their routines. What might the daily life of an everyday Hobbit living in the Shire look like?
It's not totally clear where the race of Hobbits came from, though it's theorized that they may have evolved from Men in some way. The average Hobbit lifespan is around 100 years, though there were many who lived for decades beyond that (this isn't, of course, counting Bilbo and his unusually long lifespan due to the influence of the One Ring). Hobbits become fully grown adults at 33, similarly to how Men might see themselves as adults at age 18. The most notable feature of a Hobbit, obviously, is their size, clocking in at a whopping 3 feet for the most part, though there were some who were even smaller. The Hobbits who live in the Shire tend to prefer clothing that is simple and brightly colored.
Overall, Hobbits prefer a very peaceful life, which is why both Bilbo and Frodo's decisions to go on adventures around Middle-Earth would have been so shocking for the community. Their days usually consist of a healthy mix of farming, socializing, and eating. Eating is particularly important, with Hobbits having around seven meals a day: breakfast, second breakfast, elevenses, luncheon, afternoon tea, dinner, and supper. The best way to describe the Hobbit lifestyle is that it is all about the simple pleasures, food included. Their menu usually consists of simple foods like bread, meat, potatoes, and cheese, along with sweets like cake.
Farming and gardening are the main ways that Hobbits spend their days when they're not eating. This is, of course, the main way they replenish their food supplies, as the Shire is a very insular community and doesn't interact much with the outside world. They don't use complicated machinery, opting for simple tools that they are quite deft with, such as hand-looms and water mills. Samwise Gamgee notably had a love of gardening and cooking. He is overall a great example of what a typical Hobbit and their interests and demeanor might be like, which is why he's such an interesting addition to the Fellowship. His involvement proves that even those who see themselves as ordinary or homebodies are capable of just as many great things as those with more naturally adventurous spirits, and that sometimes traveling outside of one's comfort zone isn't such a bad thing.
Other activites that Hobbits might partake in include the smoking of pipe-weed (which Merry and Pippin are often seen doing, and even Gandalf enjoys the indulgence). Hobbits love most foods, but have a particular taste for mushrooms, and many young Hobbits enjoy the activity of mushroom hunting. Frodo even mentions that he had, on occasion, stolen mushrooms from Farmer Maggot's fields, and Merry and Pippin are taking food from the fields when they come across Frodo and Sam in the Fellowship of the Ring film.
Hobbits typically reside in homes built into the side of hills, called Hobbit-holes. This is what is normally associated with them, at least, but by the third age, it was actually only the wealthier Hobbits who still lived in these kinds of houses. Many had adapted to other living situations such as large, low buildings that were structures not built into the natural landscape as Hobbit-holes were. Hobbits often held onto belongings for a long time, and anything they had no immediate use for but were unwilling to part with (just in case) was called a mathom. Their homes were known to become quite crowded with these mathoms over time, and many of the presents they gave each other were mathoms that were passed around from home to home.
The overall motto for the Hobbits is just to enjoy life as much as possible. They lead a simple life, and take pleasure in small things like food, drink, and celebration. They are just as happy to sit in each other's company as others of a different race might be to go off on an exciting adventure. It's quite the idealized, pastoral existence, and a lesson in the fact that power, glory, and wealth might not give one as much satisfaction as living a simple life would. Hobbits are connected to the natural world and tend to their fields and gardens dutifully, so it wouldn't be fair to say that they spend their lives never working - quite the opposite, actually. If multiple meals, growing food, and celebrating with parties and drinks with friends sound like a good time, the Hobbit lifestyle might just be one worth trying.
