What do you want to be when you grow up? We have heard this question many times during our school years. Perhaps, it was difficult for us to give a definite answer earlier. But now we understand that the time to choose our future profession has come. Finishing school is the beginning of an independent life for millions of school-leavers. Many roads are open before us: technical schools, colleges and universities. Centuries ago there were only a few jobs: people were farmers, bakers, butchers or carpenters. Today there are thousands of different kinds of jobs, and new ones are constantly appearing. No wonder that it is not an easy thing to make the right choice.
