Every now and then, you come across people who are filled with negative vibes. There is nothing constructive that they can ever think of about any activity at hand, individually or for the team. And it is with these people that I find working with the hardest.
Laziness and incompetence are both undesired quirks in a person. But I am fine to have people with these traits on my team than those who are pessimists.
Lazy people can be nudged with a smaller, broken-down tasks. Incompetent people can be trained. Worst case you can decide not to work with them. You only lose that one person.
A negative thought, on the other hand, is contagious — it ruins the environment in a team. It rubs off on to others, bringing down the productivity and the quality of everyone around.
It is even worse if such people are also skilled at one particular job – making timely noise. Because the noise they make first portrays the team in poor light and second dents the morale of the whole team.
Learn to not be a naysayer — wish people could be forced enrolled in such courses too.
