I wanted to kick this book after reading just half. I'm glad I didn't because this way I have no reserves on giving it fewer stars. I expected more from Mr Grant's book. I thought this was gonna reflect HIS studies and not explain what others did(the studies and the books suggested are useful, however). Also comparing Amelia Earhart(the first woman who flew over the Atlantic Ocean) and a lady, I forgot her name, that started the suffragette movement in the US, with Beyonce, Sarah Jessica Parker, and Sheryl Sandberg(who also wrote the intro) is astonishing if not laughable. If you want to read something more interesting try 'The Geography of Genius', it is way more appealing, captivating, and original. Pun intended.
