I started writing my own reviews of books as a means to have discussions with them whilst summing-up some arguments and analyses for them. And they asked for more! So, I continued.
I noticed something else: we all try to look (or feel) smarter, but this is no easy thing. Where do I start? How do I do? Who should I talk to? How long is that going to take? How expensive is that going to be?
But here is the thing: books are a great way to boost yourself because they give you a very easy (and cheap) access to the ideas and arguments of the best thought leaders.
There are two problems here: choice and time!
First, there are so many books on the market that finding the right one may become a daunting task.
Second, even if you found the book of your dreams, in reality most people never finish the (non-fiction) books they buy.
