Hi Ekta Punn
The goal is not to usurp authority over others. The goal is to behave in such a way that others hand you authority on a plate. In fact, a true leader does not go around waving their authority asking others to bow to it. A true leader sees what others do not see and helps others come to the best decision.
Your goal should be to sincerely help others, not to use your “authority” on them. If it is that they are just not happy with your disposition, you can ignore them
