“Our children evaluate themselves based on the opinions we have of them. When we use harsh words, biting comments, and a sarcastic tone of voice, we plant the seeds of self-doubt in their developing minds.... Children who receive a steady diet of these types of messages end up feeling powerless, inadequate, and unimportant. They start to believe that they are bad, and that they can never do enough.”
—Stephanie Martson (20th century)
“The rank and file have let their servants become their masters and dictators.... Provision should be made in all union constitutions for the recall of leaders. Big salaries should not be paid. Career hunters should be driven out, as well as leaders who use labor for political ends. These types are menaces to the advancement of labor.”
—Mother Jones (1830–1930)
“What we have we prize not to the worth
Whiles we enjoy it, but being lacked and lost,
Why, then we rack the value, then we find
The virtue that possession would not show us
Whiles it was ours.”
—William Shakespeare (1564–1616)
“If goodness were only a theory, it were a pity it should be lost to the world. There are a number of things, the idea of which is a clear gain to the mind. Let people, for instance, rail at friendship, genius, freedom, as long as they will—the very names of these despised qualities are better than anything else that could be substituted for them, and embalm even the most envenomed satire against them.”
—William Hazlitt (1778–1830)
