Keeping food surplus

I tried to always keep a food surplus in the game to stay ahead of the game. As long as you have more than enough food, then your civilization will survive times of trouble.

Marginal Costs/ Benefits

I feel that it is important to look at things from a marginal cost/ benefit point of view in the game and in everyday life. I say a marginal cost/ benefit point of view in the sense that you should consider only whether the additional work or price that you have to pay is the most efficient way of drawing a benefit from that input. In the game, you are trying to build a dominant and successful civilization. The only thing that you can control is the present, so it is useless to dwell on past successes or failures. For example, if you make a bad decision in the game that hurts your civilization, you should stay positive and not hesitate it making your next decisions. Bad things will always happen, but you must keep a marginal cost/ benefit point of view or else you will be hurting yourself. I feel that you should use past experiences as learning experiences instead of just dwelling on the result. In other words, it is best to stay in the present and use your knowledge to your advantage instead allowing it to be your foe.
