The best survival strategy is to fight to improve your situation, not fight to change the world.
>The moment you become a cynic is the moment you lose your connection and with it, your ability to impact things. Because a manager who has the wrong view of your corporate culture, isn’t going to change unless you inspire them to be better and that applies to everyone.
Being realist or cynical would help you recognize the situation as it truly stands without looking at it through tainted glasses. It gives you more power, not less. Also, as a cynic, your goal won't be to inspire the manager to change, because that won't be a fight you are going to win. Your goal as a cynic would be to put yourself in a better position in that company.
As a cynic, I didn't try to fight the way things are laid in the company. The moment I found a position which seemed reasonably better at another company, I gave my resignation.
