Anyone who asks you to consider the overall situation, you are definitely not in the overall situation.

Anyone who asks you to do things regardless of the cost, you are the cost.

Anyone who says that everything is for your good, don't think too much, it's all for his good.

Anyone who says that you can rest assured, you must not rest assured.

Anyone who starts with a big promise will end up killing the donkey after it has done its job.
