initiative
The ability to start things on your own without being told.
Initiative means taking action without being told to do it. When you show initiative, you see something that needs doing and you do it, rather than waiting for someone else to notice or ask you. A student who organizes a study group before anyone suggests it demonstrates initiative. A player who starts practicing free throws on their own, without the coach assigning it, shows initiative.
Someone with initiative gets things started. They don't wait around hoping problems will solve themselves or that someone else will step up. When your teacher mentions the classroom library looks disorganized, a student with initiative might volunteer to reorganize it that afternoon.
Initiative matters because life constantly presents opportunities that no one assigns to you. Nobody tells you to learn a new skill, start a helpful project, or solve a problem you noticed. People with initiative create their own opportunities instead of waiting for permission or instructions.
You'll also hear initiative used to describe specific projects or movements: “The school launched a recycling initiative” means they started a new recycling program. In this sense, an initiative is an organized effort to accomplish something worthwhile.
The opposite of initiative is passivity: waiting for others to act, doing only what you're specifically told, and missing chances because you didn't step forward. When you take initiative, you're deciding that something matters enough for you to begin it yourself.
