Here are some quotes that I find to be somewhat appropriate in today's global environment:
Moving too fast?:
"What is the use of running if you're not on the right road" - Anonymous
If only people listened to Ben (and I don't mean Bernanke. Anyways, for more of Poor Richard's pearls of wisdom click here):
"An ounce of prevention is worth a pound of cure" - Benjamin Franklin
Come on now, it isn't all bad:
"We are healed of a suffering only by experiencing it in full" - Marcel Proust (this one is too true)
"Good judgment comes from experience and experience usually comes from bad judgment" - Anonymous (I'm more experienced than I thought.)
Here is a Bonus Quote (On first reading I thought it was pretty useless but after further observations this quote was only seemingly useless):
"There is nothing in which people more betray their character than in what they laugh at" - Johann Wolfgang van Goethe
So, if you really want to get to know someone, take them to a comedy show and see what jokes they laugh at. You will be surprised at how right Johann was.
