Never nod when you don’t fully intend to commit. By doing that, you’re displaying what is called passive-aggressive behavior. Passive-aggressive behavior is when you say “yeah, I’ll do that,” but you don’t really have any intention of doing it. The problem with passive-aggressive behavior is people begin to not trust you.
If you say you’re going to do something, live your word. That’s what integrity really is. Integrity isn’t just not stealing and not doing bad things. It’s you in relationship with your word in such a way that you do what you say you’re going to do.
So, if you nod, that means your actions need to be this [nodding head] as well. By doing that, people trust you—and trust is the foundation for all relationships.
