Criticizing is easy. If people tell you that you are criticizing or being negative you probably are. I've been there, done that, there is nothing to gain from it. It is negative state of mind.
Instead of criticizing or being negative try doing. Set out to change things by doing not talking about it. Don't go to you manager with the problem or critique, go with the solution to the problem.
Problems nobody likes, solutions to the problems, on the other hand, people generally love.
