How to determine the scope of activity
Find out whether you are an extrovert or an introvert. On this depends, what kind of work and in what conditions will bring more satisfaction. Extraverts like to hang out, a lot of people, they know how to think quickly. Introverts prefer solitude, individual work, quickly get tired in a noisy team, think slowly, but study the question deeply. Some people find it difficult to determine their type, because they are inclined to both. In this case, any field of activity is suitable. People with obvious signs of something one must take this feature into account.
Make a list of possible professions. Extraverts fit any direction where activity, movement, communication with people is required. Their profession: TV presenter, sales manager, event organizer, etc. Introverts feel comfortable doing the work alone: programmers, accountants, analysts, etc. This does not mean that an introvert can not achieve success by working as a sales agent. On the contrary, it will develop weak points. But if the choice is made in favor of "native" working conditions, it will be possible to realize oneself more quickly and the work will not cause unbearable fatigue.
Find out the financial prospects for each direction. In addition to professional growth, it is important to have financial success. For some people this is not essential, but excess money opens up more opportunities for learning and recreation. In different economic periods, the same specialty can be both low-paid and vice versa. Sift directions that are not profitable in the short term.
Flip through the books for specialists of each direction. This is a test for the remaining specialties. If the books seem interesting, exciting, and you want to immerse yourself in learning the material, the specialty can be suitable. See the books of different authors, because some are boring, regardless of the subject matter.
Talk to the people of the chosen specialty. The last level of the test will show whether the options and working conditions are right for your type, defined in the first step. Note that the conversation can be conducted with a person who simply is not in his place. Such an interlocutor can criticize the choice of a specialty and recommend something to which more is located. That is why the check is conducted in several steps.
Analyze the information received, impressions and make the final choice. If you can work in the right direction, do this before you devote years of study and work.
