"Expertise pays; polymathy pays exponentially. Build a world-class skillset that will make you unique and irreplaceable. The art of becoming a polymath is really about maximizing your opportunities in life. Don't be the person with the hammer -- be the person with an entire woodshop at their disposal. Learn to think outside the box and adopt a flexible mindset. Become multi-faceted. Polymath shows you how to be a singular entity, like Benjamin Franklin, Leonardo da Vinci, and Thomas Young. No, you won't achieve what they achieved, but you will understand the skills, habits, and techniques to master multiple realms of knowledge and skills. Jack of all trades, master of none? No such thing." -- Back cover.
