Wear your ego like a loose fitting garment.

Buddha

In general, pride is at the bottom of all great mistakes.

John Ruskin

No hay nada noble en ser superior a tus semejantes. La verdadera nobleza radica en ser superior a tu yo anterior.

Ernest Hemingway

Above all, don't lie to yourself. The man who lies to himself and listens to his own lie comes to a point that he cannot distinguish the truth within him, or around him, and so loses all respect for himself and for others. And having no respect he ceases to love.

Fyodor Dostoyevsky

Do not be proud of your achievements thinking it is the genius in you; even cells have done miracles when we tinkered with their genes.

Boghos L. Artinian

When it comes down to it, I let them think what they want. If they care enough to bother with what I do, then I'm already better than them.

Marilyn Monroe
