No action, no progress and no success.

Action means your progress in your life. And progress means you’re successful in your life. Whatever you act in your life, it’ll reflect on your life, and it’ll transfer to your progress in your life, and then convert into your success. 

Inaction means your degradation in your life. And degradation means you fail in your life. Ask yourself what you want in your life: action or inaction or success or failure.
