~Albert Einstein

“Joy comes from the realization of how special the moment we’re experiencing is, such as sharing the sight of an amazing waterfall with someone dear to us, a spontaneous hug from a child, our pet’s enthusiasm at our return home, the burble of the coffee maker in the morning, curling up with a new book by our favorite author, or the sound of our name when spoken with love by our inamorato.” ~Victoria Vargas (more here)

“I can’t give you a surefire formula for success, but I can give you a formula for failure: try to please everybody all the time.” ~Herbert Bayard Swope

“Keep It Simple, Stupid”

“There are too many people, and too few human beings.” ~Robert Zend

“Smart people talk about ideas. Common people talk about things. Mediocre people talk about other people.”
