Answer:
Must is a verb, so you must use it with an action. The subject must do an action for the word to be used correctly, or to be told to do an action.
For example:
John must complete his homework before he can go out and play.
You must complete all tasks to win the prize money.
To use must correctly there must be a desired goal, but an obstacle between where the person is now and their goal.
