Why should emotions be excluded from your work or while you are at work. Depends on what kind of emotions and services you mean as well. Helping someone who is a refugee cross the border on account of emotions clouding you or some event where you are closer to the individual and hence your perspective gets skewed can prove to be improper.
However, a journalist is a humane individual like anyone else and is very much entitled to have his own emotions and thoughts about anyone and anything and expressing them is vital to the work and can add to your repute.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
