well, this may be different depending on the person, but in my opinion, Empathizing and Listening. Make an impact by using emotional intelligence through empathy and listening, can have a large impact on somebody. even something so small like asking somebody how was your day or caring about somebody.
The impacts I hope to have on my life is somebody listening to me when I’m speaking. And they acknowledge that I am a human being, and I have feelings as well as them. this might just be me, but I’d like when people share knowledge with me in a non-sarcastic way, helpful way.
i hoped that helped!
