“Those who make the worst use of their time are the first to complain of its brevity.”

“There is no necessity for pain-why, then, is the worst pain reserved for those who will not accept its necessity?”

“Those who do not complain are never pitied.”

“Going through a tough time doesn't make you a bad person. Those things define who we become. In the best of times, everyone grows and prospers. But when times are at their worst, we find out what we have in us.”

“The necessary consequence of man's right to life is his right to self-defense. In a civilized society, force may be used only in retaliation and only against those who initiate its use. All the reasons which make the initiation of physical force an evil, make the retaliatory use of physical force a moral imperative.If some "pacifist" society renounced the retaliatory use of force, it would be left helplessly at the mercy of the first thug who decided to be immoral. Such a society would achieve the opposite of its intention: instead of abolishing evil, it would encourage and reward it.”

“Complaining is the absolute worst possible thing you could do for your health or your wealth. The worst! ... For the next seven days, I challenge you not to complain at all.”
