Cannot Quotes (page 143)
It is easy to be disgruntled if you are denied rights and freedoms to which you feel entitled. But if you are not coherent, if you cannot put into words what it is that displeases you and why it is unfair and should change, then you are dismissed as an unreasonable whiner. You may be lectured about perseverance and patience, life as a test, the need to accept the higher wisdom of others.
Ayaan Hirsi Ali
In his own life, then, a man is not to expect happiness, only to profit by it gladly when it shall arise; he is on duty here; he knows not how or why, and does not need to know; he knows not for what hire, and must not ask. Somehow or other, though he does not know what goodness is, he must try to be good; somehow or other, though he cannot tell what will do it, he must try to give happiness to others.
Robert Louis Stevenson
