Make firm, consistent requests with clear limit. Praise and reward a first-time response. Impose a negative consequence if the task is not completed. If the garbage is still here, there will be no TV before your homework. Advice-Giving Lecturing is fruitless.
People have a limited attention span for monologues that involve no interaction.
And lectures often do not address the problem. Lecturing a child whose homework is chronically late about the value of an education does not address the homework issue. Advice is not fruitless, but it is often given when it is not wanted or at the wrong time. Reduce the anxiety. I see you're upset by this.
