So many professions

There are so many professions in the world. Every person may find the one that would correspond to his/her interests and tastes. But the work should always bring pleasure. If you are doing your work with pleasure, then the work is done quickly and its quality is good. But if work doesn't bring any pleasure, it can't be done properly.
There are so many various professions that sometimes a person faces a problem what profession to choose. The training to get new job may last for a long time that is why the choice should be made carefully.
Every person forms his/her own idea about the good job. For one person it is well-paid job with all modern conveniences and good colleagues. For another person it is his hobby and flexible schedule. For another person the good job is the possibility to demonstrate his/her knowledge, etc.
The list of professions is long. Besides, there are a lot of professions that appear as the development of another profession. For example, everybody knows the profession of a pilot. But this profession developed a lot and the profession of test pilot appeared. Such profession is the consequence of holding of more than one office. New professions also appear thanks to different levels and categories of the same profession.
All professions were gathered in one reference book that adds new professions regularly. This book is international one.
There are several kinds of professions. There are military (artillerist, military pilot, sapper, sniper, infantryman, etc.), economic (bookkeeper, manager, marketer, economist, etc.), medical (different kinds of doctors), educational (teacher, lecturer, tutor, etc.), technical (engineer, coder, programmer, erector, etc.), creative (actor, photographer, designer, musician, artist, etc.).
There are also a lot of professions that differ in dependence on the sphere of activity. For example there are professions in cinematography, professions in photography, computer professions, etc.
People may get necessary training in Universities, colleges and Institutes. Well-qualified people will give you all information and knowledge necessary to do your work properly.
But some professions need talent. For example it is impossible to become a painter is you paint badly. Only those who have talent become famous and rich. Talented person may find interesting occupation and earn a lot of money enjoying his/her hobby.
As there are a lot of professions, psychologists have created a great number of tests with the help of which people may choose the profession that would correspond to their interests, knowledge and abilities.
