Not only on work but in life generally. We are proven to be creators of our reality and it all starts in our minds with the thoughts we generate and emit into the infinite space that surrounds us.

That's why optimists are generally always much better of in life than pessimists.

And it's the sole reason I prohibit myself from any negative thoughts and thought patterns, completely forbidding them to enter my mind as I know they will inevitably materialize in real life.
