Hmm I went through the list.. And actually only two appealed to me.
How to earn money fast
Next week's lottery numbers
Without trying to sound like I am so money-mind, I think financial freedom is so underrated. It allows one to escape the rat race and to have so many more hours to live life to the fullest.

So there you go!
