You don’t have to try to stop what the others’ are saying. It’s a vain thing and will not labour any fruits. People just say whatever they want to say, good or bad, about you. They almost never remember your victories, but they can easily say about your downfalls and other mean stuff. Examples include:
I’m a polyglot. Who is he? [Hey *darl*, just because you can speak many languages, don’t underestimate the others if they’re trying to learn even just one.]
I’ve Macbook. You only have Acer. [No one cares if you have a Macbook. You use Mac and Acer for the same functions anyway.]
I’m fashionable. You’re just, well, not one of us. [Like being fashionable is a good thing if you’re a bimbo.]
If you’re paying too much attention to the criticisms, it will lead to your own collapse, and they like to see you when you’re in that state. It’ll make them feel more superior. It’s better to ignore all those mean critiques and just continue with your life. You know what you’re doing, not them. Prove to them that you can do better. Ultimately, you’re not doing the things you want to do to impress them. It’s for your own satisfaction. If they can see your achievements and still talk nonsensical things, just let them be. People just don’t know how to shut their mouth sometimes.
