Answer 2: Think twice. Yes, there is a direction, and it is ok to think for the sake of direction. Doing, there is behavior, for the purpose of directional implementation. Thinking is better than doing. No matter how much you do, think about it. Thought and action should be unified. Unified as a destination. Do after positioning, think about how to do it, and measure after thinking. The process of doing can not be idealized, so thinking is mainly aimed at the destination, and thinking at this time is doing; Doing can improve thinking and become the result of thinking. Thinking without doing is empty. Action without thinking is immature.
