Yes. Conversing with people requires some amount of empathy as you must consider someone else's words in order to be in a state of listening. It's not distinct from "real life". _It is_ your life.
> "... win you anything big"
It's just my impression, and I could be mistaken, but this sounds overly pragmatic. Living life this way leads to getting entrenched in local maxima. It's better to also consider what others want and find compromise. What you sacrifice in absolute immediate gains, you exchange for longer term possibilities and networking.
On the flip side, don't burden yourself with responsibilities that don't interest you, and don't compromise with people who won't appreciate it.
All that said, what I "won" is my social life and career which I am grateful for. To answer if it's anything "big" is all relative. It's a big deal to me. There's no need to be braggadocious. Life is what you make it.
