STEM stands for Science, Technology, Engineering, and Mathematics in English. These are all important areas that a young person must master if he wants to create his projects. It is important that future inventors carry a large number of science-related courses from the school. Courses in technology and engineering should also be taken. But in addition, it is very useful to have notions of computer science or carpentry.
To be an inventor, you just need some creativity and sensitivity to find a solution to the problems that surround people. A good invention is not only focused on large machines or super modern cars, but it can also be something as simple as a pen.
