I once saw a really interesting discussion about when it's appropriate to break things off. The best answer is: when you're ready to accept all the consequences.
So sometimes, when someone seeking cooperation encounters obstacles, instead of reflecting on their own issues or figuring out how to resolve them, they blindly blame the other party, eventually losing their composure and lashing out in anger. I can't help but wonder: is this staff member truly a fully autonomous individual? Have they clearly understood their own goals? The distinction between acting on impulse and considering the bigger picture seems blurred here. No matter the outcome, they just can't bear being wronged or insulted—they must retaliate with insults.
I ask you: if everyone in the market operated with this attitude, how many projects would truly stand out in the end?
Fortunately, most people are rational, and most adults are mature. When problems arise, they manage their emotions and focus on solving the issues. What else could possibly be troubling?
