This Top 10 Smartest People infographic displays the 10 people in the world with the highest measured IQs. It appears that being smart really does get you ahead in life. People on the list include actor James Wood, co-founder of Microsoft and billionaire Paul Allen, Stephen Hawking and a physicist at the top of his field who has done so while battling ALS.
It is truly amazing what the human mind is capable of. This list of the Top 10 Smartest People can act as a motivator for all those who don't have quite so big a brain (that's how it works, right?)
One last thing to note is that there are different types of intelligence, and IQ tests can't standardize intelligence over so many diverse fields. It's likely that these geniuses would tell you the same thing.
