"All that we are is the result of what we have thought: it is founded on our thoughts, it is made up of our thoughts. If a man speaks or acts with an evil thought, pain follows him, as the wheel follows the foot of the ox that draws the carriage... If a man speaks or acts with a pure thought, happiness follows him, like a shadow that never leaves him." --Buddha
I love this quote. It is a reminder that you are what you think. If you think positive, positivity will follow you. If you think negative, then negativity follows. Picture it in your mind and you can accomplish anything.
