"I will Teach You To Be Rich" is an amazing book by Ramit Sethi.
I am an ardent follower of his blog, and it looks like he has new insights almost every day.
His frat-boy like comments, yet buffet-type insights really strike a chord with today's generation.
Currently, I am saving up some money to enroll for his "Earn1K" Course. It is supposedly great for freelancers.
