You can’t be a leader, let alone a good leader or an effective one, if your first instinct is to respond to any input from others by dismissing or demeaning them personally. When you make it clear to others that any suggestion, constructive criticism, complaint, or inspiration will be met with condescension, they will learn that their thoughts are not wanted or welcome, and will oblige your demonstrated wishes by keeping such to themselves – to your detriment, and the detriment of your organization as a whole.
