Do not handicap your children by making their lives easy.
		-- Robert A. Heinlein

Do not meddle in the affairs of troff, for it is subtle and quick to anger.

Do not meddle in the affairs of wizards, for you are crunchy and good
with ketchup.

Do not meddle in the affairs of wizards,
for they become soggy and hard to light.

Do not throw cigarette butts in the urinal,
for they are subtle and quick to anger.

Do not overtax your powers.

Do not read this fortune under penalty of law.
Violators will be prosecuted.
(Penal Code sec. 2.3.2 (II.a.))

Do not seek death; death will find you.
But seek the road which makes death a fulfillment.
		-- Dag Hammarskjold

Do not sleep in a eucalyptus tree tonight.

Do not stoop to tie your laces in your neighbor's melon patch.

Do not think by infection, catching an opinion like a cold.

Do not try to solve all life's problems at once --
learn to dread each day as it comes.
		-- Donald Kaul

Do not underestimate the power of the Farce.

Do not use that foreign word "ideals".  We have that excellent native
word "lies".
		-- Henrik Ibsen, "The Wild Duck"

Do not use the blue keys on this terminal.

Do not worry about which side your
bread is buttered on: you eat BOTH sides.

Do nothing unless you must, and when you must act -- hesitate.

Do, or do not; there is no try.

Do people know you have freckles everywhere?

Do something unusual today.  Pay a bill.

Do students of Zen Buddhism do Om-work?
