If you do not know what you’re doing, do it neatly.

If you do not like the answer, you shouldn’t have asked the question.

If you do not make dust, you eat dust.

If you do not say it, they can’t repeat it.

If you do not understand it, it must be intuitively obvious.

If you explain so clearly that no one can possibly misunderstand, someone will.

If you file it, you’ll know where it is but never need it. If you don’t file it, you’ll need it but never know where it is.

If you have always done it that way, it is probably wrong.

If you have got them by the testicles, their hearts and minds will follow.

If you have nothing to do, don’t do it here.
