He was rated "dull, slow, and impractical" by his teachers and was asked to leave college. Despite this negative start, he was awarded a patent for the rotary steam engine before he turned twenty. His next invention, a device that put derailed trails back on track, was purchased by virtually every railroad in his country. Before this man's creative life was over, he patented over four hundred inventions and amassed an industrial empire that few have equalled.
Even though he was disabled near the end of his life, he continued to invent, using his wheelchair to transport him from one project to another. He died surrounded by the sketches of his latest project - the motorized wheelchair.
The man labeled as "impractical and dull" was named George Westinghouse. He refused to accept the negative opinions of those around him and instead chose to become one of the richest and most creative men in history. I hope you choose to believe in yourself and strive for your goals even if others express negative opinions of your abilities.
