Fear of Competition

"You need have not fear of competition from the person who says, 'I am not paid to do this and I will not do it'.  He will never be a dangerous competitor for your job.  But watch out for the fellow who remains at his work until it is finished and performs a little more than is expected of him, for he may challenge you at the post and pass you at the grand-stand."

-- Napoleon Hill


"The way Khan portrays the concept of education and the mechanism of learning is revolutionary."

-- Bill Gates


"There are times when we may fool ourselves. There are times when we can fool others. But we can never fool our body. It is the most sensitive barometer of our inner world."

-- Sherrill Sellman
