attitude
The way you think, feel, and act toward things.
An attitude is the way you approach situations and interact with the world around you. It's the mental stance you take toward people, challenges, and experiences. When your teacher says “check your attitude,” she's noticing that you're being negative, dismissive, or disrespectful. When a coach praises your positive attitude, he's recognizing that you stay encouraging and energetic even when things get tough.
Your attitude shows in everything: how you talk, how you carry yourself, even your facial expressions. Two students might face the same difficult math problem, but one approaches it with curiosity and determination while the other complains that it's too hard before even trying. That difference is attitude.
A bad attitude makes things harder. It pushes people away and turns small problems into bigger ones. A good attitude doesn't mean fake cheerfulness or pretending problems don't exist. It means facing reality with resilience, treating others with respect, and staying open to learning.
People also use attitude to describe confidence or boldness, sometimes with admiration: “That gymnast has real attitude on the balance beam.” Here it means a fearless, self-assured presence.
