We all know such people, the ones who notice every step you take, every little joy, every small achievement, yet feel bitterness instead of happiness. Jealousy isn't just a feeling; it's a poison. Instead of building their own lives, they waste energy hating yours, hating how you rise, how you shine, and how you stay true to yourself. They twist your success into their sorrow, your happiness into their wound, and see your growth as their threat. The saddest part? They don't even realize how badly it's destroying them from within.
