I would add: learn to be disagreeable in a polite / professional way.

Too many people think that being disagreeable means being rude, cruel, or impolite.

As a result, they just shut their mouths. But this isn’t optimal behavior for career advancement.

The ability to assert one’s disagreement unemotionally and respectfully is a highly valued trait.

I’ve also noticed this on Substack.

When I get in a disagreement with someone, but they are polite and respectful, I instantly like that person, even if I disagree.

On the other hand, if someone overall agrees with me 99%, but they are rude about the 1%, it’s an instant dislike.

Being a conformist and constantly giving positive feedback can only get you so far. That’s a follower role. Leadership is a prized skill, and it requires the art of disagreement.
