Our thoughts largely shape our reality. If we have persistent negative thoughts and only focus on the negative aspects in life then we may have a negative view of reality and the world in general. If we change our thoughts to a more positive perspective and focus on the positive in the world then we see the worlds beauty.
I like to think of this topic in terms of preserving the planet. If we think the world is a negative place with little hope for positive change, then we may perpetuate that idea and let the world fall apart. However, if we see the beauty and positivity in life, we may work hard to preserve the planet and fight to make the world a better place. Good message to start my Saturday. Thanks!
