Aimless means without a clear direction or purpose.
When people say someone is being aimless, they usually mean that they don't have a specific goal in mind and are drifting through life. This can be when you're deciding what to do with your weekend, but then you end up sleeping the whole day. It's also common in conversations about plans for the future: "I was thinking of traveling, but it's hard to plan something aimless." Sometimes, being aimless is used as a joke or an excuse for procrastination – "I meant to clean my room today, but I got caught up in watching YouTube and lost all sense of direction!"
Without aim, purpose, or direction.
Example: an aimless life
