How does an opportunist operate?

People are 100% fake. I have never seen a genuine person in my life. They all have their tricks and their games. It takes time to understand the situation with all the details. You might consider the damage and accept it the way it is. But the best thing to do is to use their tricks against them in public. Develop your own game. Make sure to make it the last thing they expect. You have to be calm, patient and very smart. It is hard but very effective.
