What kind of advice would you give to be assertive? What role does being assertive play in handling criticism? In effective communication?

The difference between assertive and aggressive behavior can be seen in how one expresses themselves, the way they respond to situations, and their body language. Being assertive is about standing up for oneself and communicating clearly with respect for others; whereas being aggressive can involve intimidating behavior or vocal outbursts aimed at dominating (Hudson & Chandler 2014).
