非利不動,非得不用,非危不戰。主不可以怒而興師,將不可以慍而致戰;合于利而動,不合于利而止。怒可以復喜,慍可以復悅,亡國不可以復存,死者不可以復生。故明君慎之,良將警之,此安國全軍之道也。

“Troops are not to be led to battle unless confident of success.”
Numquam ad certamen publicum produxeris militem, nisi cum eum uideris sperare uictoriam.
De Re Militari (also Epitoma Rei Militaris), Book III, "Dispositions for Action"
Context: An army is strengthened by labor and enervated by idleness. Troops are not to be led to battle unless confident of success. (General Maxims)

CBC Documentary: How To Go Out of Your Mind: The LSD Crisis (1966)
Context: We always have urged people: Don't take LSD unless you are very well prepared, unless you are specifically prepared to go out of your mind. Don't take it unless you have someone that's very experienced with you to guide you through it. And don't take it unless you are ready to have your perspective on yourself and your life radically changed, because you're gonna be a different person, and you should be ready to face this possibility.
“Never stick your hand out and let someone squirt something into it unless you know what it is.”
