If you listen to critics for too long, you will become deaf to success.

There is no greater beast than envy, no greater thief than fear, no greater enemy than greed, no greater predator than wrath, and no greater poison than bitterness.

Most people throw away their personal power... If you want to know where, look at who and what you hate, blame, resent, and envy.

The bigger the bricks critics throw at you the bigger the palace you are going to build.

Envy suggests inferiority.

Is it not strange that the more someone has, the less he feels he has? Envy can never be sated.

[M]en, though they know full well how much women are worth and how great the benefits we bring them, nonetheless seek to destroy us out of envy for our merits. It's just like the crow, when it produces white nestlings: it is so stricken by envy, knowing how black it is itself, that it kills its own offspring out of pique.

The demand for equality has two sources; one of them is among the noblest, the other is the basest, of human emotions. The noble source is the desire for fair play. But the other source is the hatred of superiority. At the present moment it would be very unrealistic to overlook the importance of the latter.

Don't try to impress a loser because If one is not happy about the things happening in their life, one cannot be happy about the things happening in someone else's life.

It is in vain to try and stop a star from rising, even with a ladder.
