What is a word you feel that too many people use?
“A word I feel too many people use is ‘Impossible’. In the armed forces, we are taught that nothing is truly impossible — it’s only a matter of preparation, persistence, and teamwork. The moment we label something as impossible, we stop looking for solutions. For a soldier, every challenge is a mission, and every mission has a way forward.”

Here are three solid options with reasoning from an armed forces perspective:
Impossible – It shuts down initiative and problem-solving before you’ve even tried. In the forces, every challenge has a way forward if you have the will, skill, and teamwork.
Can’t – A small word, but it breeds self-doubt. The armed forces thrive on confidence and determination; “can’t” is replaced with “will find a way.”
Someday – It delays action. In the military, missions have timelines, and “someday” is just another way of saying “never.” Action is taken here and now.
