Rich Dad, Poor Dad: What the Rich Teach Their Kids About Money–That the Poor and the Middle Class Do Not! by Robert T. Kiyosaki
I recommend reading this book to understand the foundation of how society works in terms of money and why you should pursue to learn skills within; Starting a business, Real Estate Investment and Investing in the Stock Market. The book is an easy read and it really opened my eyes when I read it. The Rich Dad Company have written a whole load of other books that also are good as well as a boardgame (that I recommend buying).
