"Without Knowledge, Skill cannot be focused. Without Skill, Strength cannot be brought to bear and without Strength, Knowledge may not be applied." - Alexander the Great's Chief Physician
"You may fool all of the people some of the time, you can even fool some of the people all of the time, but you cannot fool all of the people all of the time." Abraham Lincoln
"Lead me, follow me, or get the hell out of the way." George Patton
A favourite of mine is a pseudo 'inspirational poster' quote:
Eagles may soar but weasels don't get sucked into jet engines
:lol:.
But a core tenet that I always try to remember and sometimes forget is one I posted very recently here at MT with regard to the brevity of life and the importance of retaining a sense of perspective:
"Out, out, brief candle! Life's but a walking shadow, a poor player that struts and frets his hour upon the stage and then is heard no more: it is a tale told by an idiot, full of sound and fury, signifying nothing.".
I have to say that if you ever need to delve into either inspiration, wisdom or plain truth about the human condition, you wont go far wrong with Shakespeare.
