Isaac Newton’s third law of motion is:
When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.
Paul McCartney, of The Beatles, wrote in their song The End:
“And, in the end
The love you take
is equal to the love you make.”
Life is similar. Want recognition, reputation, love, money, friends? What you put out into the world is what you get back — it isn’t always equal — but you will get something in return for your efforts. Give nothing, get nothing.
