Those who are believed to be most abject and humble are usually the most ambitious and envious.

- Baruch Spinoza

Feelings like disappointment, embarrassment, irritation, resentment, anger, jealousy, and fear, instead of being bad news, are actually very clear moments that teach us where it is that we're holding back. They teach us to perk up and lean in when we feel we'd rather collapse and back away. They're like messengers that show us, with terrifying clarity, exactly where we're stuck. This very moment is the perfect teacher, and, lucky for us, it's with us wherever we are.

- Pema Chodron

Jealousy is the tribute mediocrity pays to genius.

- Fulton J. Sheen

Mediocrity doesn't mean average intelligence, it means an average intelligence that resents and envies its betters.

- Ayn Rand

Whenever a friend succeeds, a little something in me dies.

- Gore Vidal
