And I got the book mentioned in the article - The Luck Factor by Richard Wiseman.
One of the exercises in the book is to think over how things have unfolded in your life - what would have happened if you took left inside of right when you met your partner or got a great job? And when I thought it over, there has been some element of luck involved. At my first job I wasn't supposed to be there for an interview but went along with a roommate as I had nothing better to do.
Now I believe sure you can work hard and do most of the work in Naval's list but all of it will ensure you are lucky when you run into one of the long term people in a long term industry. And everything will fall in place.
