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
