Firefighting is a calling. Not everyone can become a firefighter. Not every Australian is suitable for firefighter recruitment. Some people are born firefighters while others make themselves to be firefighters.
Firefighting profession has financial rewards. Firefighters earn a monthly salary. They are also entitled to a pension.
A firefighting profession also has emotional rewards. The thought of saving people from a fire is very satisfying. It will leave with a person for the rest of his life. No amount of money can compensate for saving lives.
Firefighters put their lives on the line to save the lives of other people. That is the height of sacrifice.
A firefighter needs to have physical and mental skills. Fighting a fire is a physically exhausting endeavor. One has to lift heavy pipes. A firefighter should determine the best way to get into a burning building. That will require intelligence.
