Cool poster in the London tube

Guys, a simple, yet powerful message: find your balance in the smallest things in life!

Text of the poster (in case it's not readable):

"Certain was the alarm going off this morning. Not so certain was getting out of bed. Certain is the sun rising. Not so sure is that it will shine. For all life's certainties there are still plenty of uncertainties. We won't even talk about the state of the economy or whether Obama is really up for the job. But fortunately there are some things you can predict. You don't know why they happen, they just do and you can rely on them to happen day in, day out. Take this poster, for instance. Come rain or shine, you can be sure that there will be something here to read, transporting you away for three minutes while you wait for your train. Maybe once you've read it, you can even strike a conversation with the person standing next to you. Then again, maybe not. We know that now and again it's good to have a few constants in your life. One thing you can always be sure of is that this poster, or another one just like it, will be here to fill those few empty moments in your otherwise busy day."
