On the contrary. It is much easier to criticize than to persevere in the face of criticism.
What part of what I describe above isn't perseverance?
Perseverance is when one stays at one's post and finishes the task to which one is elected. Sarah Palin has not persevered. She quit. Yes, I know why she quit--because the phony ethics lawsuits forced her to hire counsel and it was costing her big bucks and keeping her from doing her job. What will she do when the lefties come after her as President? They will hit her with all they've got. Will she stay at her post and persevere? She doesn't have a very good track record.
