When you are confused, I suggest you read two books——
1. On Protracted War by Jiao Yuan: Look at strategy and tactics from a materialistic perspective, deploy troops, food and weapons, start with the heart and take action as the basis.
2. Xunzi's Theory of War in Zizhi Tongjian: The greatest knowledge is to abandon doubts, the greatest action is to avoid mistakes, and the greatest thing is to have no regrets. When there is no regret, stop, it is not necessary!
