Cost of my rigidity!

The cost of advice that I ignored because I thought I knew more.

The cost of not paying enough attention to listening while I was preparing my response.

The cost of pretending to be busy and not giving my full attention.

The cost of thinking—it is not my problem, and hence I am not taking any responsibility.

The cost of winning an argument.

The cost of rejecting good advice out of insecurity and jealousy.
