I am a big quote guy, one of my favorites has been " If you fail to plan, you plan to fail "....,makes you think :-)
But this landed in my favorites book also....
A wise man once said " Knowing oneself and knowing the enemy, in every battle certain victory. Knowing oneself, not knowing the enemy, one victory for one loss, but not knowing oneself and not knowing the enemy, in every battle certain defeat.
Riddles are also awesome......those that will make you think for weeks until you figure it out
