How to save your money in a smart way

1. Make the most possible of what you spend on luxury and entertainment. For example, almost all the books, movies and magazines you need are free online, so you do not have to buy everything you need.
2. Save on your car. When you buy an unused and very modern car, you will lose 25-40% of its value after a year or two, according to car experts. But if you buy a good two-year-old car, it means that the previous owner has paid you 40% of its value. It is also preferable not to buy a very old and decrepit car that requires a lot of repairs constantly.
3. Spending on food. Many of us spend a lot of money on the food they eat, although there are many ways to change part of our diet in a way that makes it healthier and less expensive.
4. Spending on expensive brands. Many industries are similar, and you may find the same product the same specifications and quality cheaper than others because it bears a different name. 
5. Save on energy expenditure. There are many ways to save household electricity and energy by acquiring devices that require less energy and the same quality and efficiency.
6. Save on personal expenses. Too much money is spent without notice, both on the mobile phone and the Internet, although you can reduce unnecessary calls or sign up with a cheaper service provider.
7. Get rid of the credit card because it makes you spend without realizing that you spent a lot, maybe because you do not get the money out of your pocket, but you come out with a card that does not feel the difference between spending $ 20 or $ 200.
8. Remember that you save money to collect for the future if you need it, not to spend it later on more expensive items.

10 inventions we need in the future

1) Computer DNA

The DNA of each human being can store too much genetic information, since a milligram of DNA can store any information that has occurred all the time. Imagine if a computer with this technology was invented in storage.

2) Colonization of the moon

The world is still waiting for the genius who will be able to invent rooms and buildings that can be created in outer space. If so, it is easy to access and colonize the moon, because life on Earth has become very crowded, a project where NASA has not yet succeeded.

3) Head transplantation

Some may think that doing such operations is a bad form of medicine, but if we think a bit about the head transplant, we will find that it has benefits if it succeeds in the future, as if a person can get rid of his body with a type of disease that has not yet moved to his head.

4) Clean energy

As you read this list, the earth’s stock of fuel may end up. Some studies say that the earth’s oil reserves will be over in 55 years, so humans need to invent a new energy source and be environmentally friendly.

5) Cure for cancer

There is no radical cure for cancer that kills 7 million people a year in the world, prompting scientists to seek as quickly as possible a cure for the disease.

6) Travel to Mars

After the man was able to walk on the moon, the idea was to travel to Mars to travel on its surface also, which scientists are now working on to travel to Mars and discover the possibility of living on it or not.

7) Space elevator

This elevator will not be inside an apartment building, but it will connect between the earth and the moon or any spaceship in outer space. Such an invention, if constructed, would make humans able to travel to outer space very easily.

8) Theory of everything

Scientists around the world know that anything that happens around us must have a specific cause, but what scientists find difficult is to find out what causes what is happening in the world. If scientists know the theory behind everything, All they want.

9) Nanotechnology

Nanotechnology can change the course of history for drug science, and if successfully completed, doctors will be able to kill all cancer cells in the body.

10) Access to the Earth Center

In the past, most people believed that access to the center of the earth was easy, a misconception, because the pressure in that area was so great that no human could afford it. If anyone could get there, they would certainly discover new sources of energy.
