Who is another person besides Buddha who left a life of luxury in order to pursue wisdom?

Oh, dude, like Siddhartha Gautama, who later became known as Buddha, isn't the only one who ditched the fancy life for some deep thinking. You've also got Diogenes, that ancient Greek dude who gave up his wealth to live like a homeless philosopher. So, yeah, there's more than one rich person out there who decided to swap the bling for some brainpower.
