And what I've learned from that book is linked somewhat to what some now very popular books like 'The Secret' from Rhonda Byrne are preaching... What you think is what you attract, focus on positive thinking.

Interesting, the insight is quite simple, be aware of your thougths! If you are aware, you will often realize that most of the negative thougths are quite unrealistic! Sometimes we paint some negative scenarios in our minds that are high unlikely to ever happen!
On the positive side, these thoughts are useful as their purpose is to protect us from hurt, from wrong decisions, etc. But on the other side, most of them are unrealistic and will only prevent us from doing things, taking action, taking control of our life and moving it forward!
