The great inventor Thomas Edison is one of the best examples of a successful state of mind. According many popular stories Thomas Edison was asked after several thousand attempts to invent the electric light bulb without success, how he would handle his failure. Edison stated that he had not failed, but rather had produced several thousand outcomes which would lead to success. Several thousand outcomes later Edison successfully produced the electric light bulb, whether consciously or unconsciously, Edison had to program his mind and body to channel his energy into a successful outcome.
A popular myth or a true story?
There are actually two documented variations of a quote by Edison where he downplayed his failures, but focused on his success.
According to Rutgers, Myth Buster: Edison's 10,000 attempts, "The source of the story about Edison trying thousands of experiments or materials is probably an 1890 interview in Harper's Monthly Magazine."
