I came across this article on lifehack.org, “8 Essential Skills They Didn’t Teach you in School” and I feel that readers and contributors to this blog will be able to add valuable skills of their own they think should be on the list or further links to the 8 topics… but that is because I assume everyone reading this blog is smarter than the average bear 
- How to make people like you and network
- How to speed read (spreednews.com) and the power of audio books
- How to set goals and manage time
- How to read a financial statement
- How to negotiate, read contracts and not get taken advantage of
- How to save and invest
- How to be sucessful in life
- How to spread an idea and basic marketing
Now this may be close to #5, but here it is anyways
#9 Learn to be aggressive; read the Art of War, by SunTzu and The Prince by Machiavelli. You master the art of aggression and learn to control it, you will be laughing
Sorry, here are links to both of those books
