BEING A JOURNALIST: EXPECTATIONS AND THE REAL
WORLD
Being a journalist is a profession full of dreams and desires, and since the
beginning of the process to become one, the student has to face the contrast between
the university and the real environment, because journalism has an advantage, that
can be disadvantage too. That is, that everybody can look at the work that a reporter
does, because this is the real meaning of journalism, to work for the community and
for the public cause. Being in the front of the reality and in the center of illusions is
the place in which the students can see the roads they can follow in the real world.
Money, ethics, ideals, micro or macro-media? That becomes a dilemma when the
world is in front of its expectations, and when life and people begin to remind them
that, as teachers use to say:” this world can chew you up and spit you out.”
What is the Ideal Training for Journalism in the UK? There isn’t any really.
But I think you can make a case for at least a theoretical ideal. That is to go to a firstclass
college for liberal-arts course, while working on a school paper. Also, while
still in college, you should get a job on a weekly or daily newspaper during summer
vacations. This is almost certain to lead to a full-time job after graduation. And then,
after one or two, perhaps even five years as a reporter as a desk man, you can go to
a journalism school that offers graduate instruction. By now you will have learned
from experience what it is in journalism that you don’t know well enough. And you
can take both journalism and academic courses, and perhaps specialize in your
chosen field of municipal government or science or history or literature or whatever
you prefer. The only hitch in this plan is that, once most of us get a full-time job,
with an attendant monthly salary, it is not easy to give up that salary and go back to
school.
