First and foremost, be faithful to your superiors, keep all promises, refuse the friendship of all who are not like you; and if you have made a mistake, do not be afraid of admitting the fact and amending your ways.
Most business mistakes are irreversible setbacks, but you get another chance. There are two things in life that you don't get another chance at - marrying the wrong person and what you do with your children.
It is a mistake to confound strangeness with mystery. The most commonplace crime is often the most mysterious because it presents no new or special features from which deductions may be drawn. This murder would have been infinitely more difficult to unravel had the body of the victim been simply found lying in the roadway without any of those outré and sensational accompaniments which have rendered it remarkable. These strange details, far from making the case more difficult, have really had the effect of making it less so.
Buying books would be a good thing if one could also buy the time to read them in: but as a rule the purchase of books is mistaken for the appropriation of their contents.
Don't ever mistake my silence for ignorance, my calmness for acceptance or my kindness for weakness. Compassion and tolerance are not a sign of weakness, but a sign of strength.
We're taking action against evil people. Because this great nation of many religions understands, our war is not against Islam, or against faith practiced by the Muslim people. Our war is a war against evil. This is clearly a case of good versus evil, and make no mistake about it - good will prevail.
It is not a mistake to commit a mistake, for no one commits a mistake knowing it to be one. But it is a mistake not to correct the mistake after knowing it to be one. If you are afraid of committing a mistake, you are afraid of doing anything at all. You will correct your mistakes whenever you find them.
I wanted to eat of the fruit of all the trees in the garden of the world… And so, indeed, I went out, and so I lived. My only mistake was that I confined myself so exclusively to the trees of what seemed to me the sun-lit side of the garden, and shunned the other side for its shadow and its gloom.
Of course, there is no question that Libya - and the world - will be better off with Gaddafi out of power. I, along with many other world leaders, have embraced that goal, and will actively pursue it through non-military means. But broadening our military mission to include regime change would be a mistake.
