don't speak often, but prepare well. 
repeat good talks. 
win reputation and confidence of a good speaker. 
speaking is efficient since any minute your number of listeners spent that minute listening.
	don't waste their time. 
	if you have nothing to say, don't say anything and be brief with it. 

Churchil:
^^^^^^^^^

start strongly: no joke, but a quotation, a drama, or an anecdote

theme one: single message

simple language 

paint a picture orally: iron curtain!! 

end emotionally: pride, love: country, people, god!!

Don't talk about World War 2. Talk about the battle of the bulge. Talk about a day in the battle
of the Bulge. Talk about private Tom at that day in the battle of the bulge.

Write slides first! 

An presentation is 90% an advetisement and only 10% an information carrier.
Books, lectures etc are 90% information carrier and 10% advertisement (are 
they?)

one or two strong messages (possibly only one): keymessage 
if possible in a single image: key image

avoid topics where you can not add much new information
if things are abstract: show a single detailed example
	(certain things cannot be explained but must be experienced) 
Avoid side tracked statements: 
	don't talk about anything that deserves a presentation by itself
	your audience will not understand your point

structure talk: 
brief problem (one sentence)
great solution (one image)

details: 
problem exactly
solution detailed
possible improvements
summary state of affairs
