Wise men and philosophers through the ages have disagreed on many things, but most seem to agree on one - "We become what we think about".
A man is what he thinks about all day long. - Ralph Waldo Emerson
A man's life is what his thoughts make of it. - Marcus Aurelius
As a man thinks in his heart, so is he. - The Bible
It is when we fill our minds with negativism that the world becomes evil. (The beast is within.) Everything we experience and everybody we encounter will carry the scent we hold in our mind.
Everything is a matter of perception; everything is relative, to you. You can choose to see a diamond or a rock. You choose the spectacles you wear - choose blue ones and the world is blue, choose green ones and the world is green.
Beauty lies in the eyes of the beholder... Cliche! Cliche! ... If you don't have beautiful eyes, everything is ugly!
