I like this one by Charles Darwin my dad often quoted it!

"A man who dares to waste one hour of time has not discovered the value of life."

"All life is an experiment. The more experiments you make the better."

- Ralph Waldo Emerson

Once gone we consider the bright times

The remnants keep us forever in rhymes

"Our prime purpose in this life is to help others.

And if you can't help them, at least don't hurt them."

- Dalai Lama

Life is also 

Too much politeness can kill thoughts. 

''Poetry is when an emotion has found its thought and the thought has found words.''

-- Robert Frost

"What do we live for, if not to make life less difficult for each other?" 

-- George Eliot 

I am a 60 year old living on campus. What I can see from a bus stop waiting for a bus is college students walk in crowds not groups! Gosh! I don't think that is easier for anyone this day and age. Unless you're a college student!
