That's one way of looking at the world, I think. But when you choose to work with those who view life this way, it can be very difficult to stay in the game - for many reasons. In corporate America, it seems to be fairly common to withhold information from others as part of game strategy.
The less others know about your cards, and how you intend to play them, the less likely you are to get in their way. The less others know about your needs and commitments, the less likely it is that you will know when and if they change, or need to know why.
But the result of all this card holding is that people learn to trust you less, do not take your statements or requests at face value, and begin to hedge their bets. After a while, it just gets tiring and some perfectly good 'players' just walk away from the game.
There are many ways to view life. And our view of what life is about affects the way we live from day to day, moment to mement, and the way we treat or use others.
I prefer to see life as a journey of exploration and adventure. I meet a lot of wonderful and weird creatures along the way, and it's all about the journey, the experience. True companionship, warm and honest friendship and cooperation is what I value. For me, it's not a game at all.
