1. Living with Family Members or Roommates
If you are living by yourself, then you have to pay for ALL your expenses with your own money. If you live with roommates or family members, then you just have to pay part or none of the living expenses. In addition, you gain vital social skills and coping skills, as you socialize with your family and roommates on a daily basis. So, it is considerably more economical to live with family members or roommates than to live alone.
2. Carpooling
Compared to a human, a car is usually a big piece of machinery. This big machine requires gas, oil changes, and check-ups every now and then. To save money on gas, carpooling is the way to go. If you and your roommates/family members/friends share the same destination, then you can all ride in the car together at the same time. The person who begins the day earliest and the person who ends the day latest will set the times of going to school/work/other destination. Carpooling is an efficient way of transportation, because the car carries as much people as possible from Point A to Point B.
3. Biking
Sometimes, you want to travel to some place locally, but you don't want to bring a whole gang of people with you. So, you ride on a bicycle. A bicycle is powered by mechanical energy -- your energy. While you do have to invest a lot of your energy into propelling the bicycle, you can easily replenish the loss of energy by increasing your energy intake through the consumption of nutritious food that would help build those leg muscles.
It may be useful to consume foods that can be usable. Your body has no use for propylene glycol, so you may want to avoid that store-bought muffin. And you probably don't want to make your own muffins, because muffins are dough-based and thus require much preparation. Muffins must contain added sugar, and you can get all the sugar you need from eating fresh fruits. It may be best to reserve muffins only on Big Holidays (Yuletide [aka Germanic Christmastide], Chinese New Year, Mid-Autumn Festival, Dragon Boat Festival, Passover, Hanukkah), when you can stop your normal diet and feast on traditionally luxury food items that are rich in meats, sugar, fat, and salt. 
4. Serving Home-Cooked Meals in Big Batches
Cooking is generally a time-consuming process. However, there are lots of simple, quick recipes. Eating salads and crudités just requires you to wash the foods; stir-frying foods is a fast method of cooking. Making soups is not fast, but it is extremely simple, because all you have to do is put things in a slow-cooker, set a button, and wait until the food is ready.
Because time is so valuable, it may be very resourceful to make big batches of food all in one time and preserve the food in the freezer. Then, you and your housemates can have frozen meals every day. All you have to do is put the food in the microwave/oven/steaming basket/pot and serve.
5. Buying Things on Sale
First of all, you should buy things that you really, really, really need. If you can live without it, then that thing is probably not worth buying anyway. Typically, things that are created for leisure and pleasure are wholly unnecessary. This may include make-up, trendy clothes, sex toys, chocolate, fine wine, fancy tech gadgets, and other cool stuff. Ideally, you want to reduce your lifestyle to that of a religious ascetic. Realistically, popular indulgences are irresistible, but if you do succumb to your temptations, then you may experience a great helping of guilt along the way. That's just life.
6. Reduce, Reuse, and Recycle
Reduce consumption. Eat for your nutrition, not for your pleasure. Avoid buying luxury goods, like large pizzas or expensive cars. Reuse the things you already bought. Recycle as much as possible. Paper, plastic, glass, metals, you name it. Being environmentally friendly not only benefits the planet; it also helps you save money.
7. Financial Budgeting with Spreadsheets
Keeping track of your income and expenses lets you know whether you are overspending in a particular area. You may make effective decisions that cut back on spending and allocate money to something else. You should always make sure that you are living below your means and that your identity is secure from theft, and budgeting is a good way to do that!
8. Planting a Mini Garden
You may think that planting a mini garden is time-consuming and difficult. However, that depends on what type of plant you are planting. If you grow green onions, green nira, dandelions, wheatgrass, or basil, then you can just keep them in cups near windows as house plants.
9. Doing Things Manually
Instead of putting dirty dishes in the dishwasher, you put dishes in the sink and wash the dishes by hand. Then, you store the clean dishes into the dishwasher or a cupboard. Instead of using a gasoline-powered lawn mower, you use a man-powered lawn mower. Instead of using a leaf blower, you use a rake and a broom. Instead of using a snow blower, you use a snow shovel. The man-powered tools may make your life difficult, but look on the bright side! At least you are saving money on gas, water, and electricity! The only downside is that you'll be spending your own energy reserves on your body to do the work.
10. Learning How to Fix Things Yourself
If you know how to fix things yourself, then you can save a lot of money. Unfortunately, fixing things may require some technical skills. Lack of technical skills can lead to physical injuries or even death. So, this may be one area where you should leave the job to a professional.
