Does hard work always lead to success?
Oh god no. Success is the carrot used to spur hard work. Most of the time for most of us, it is a lie. Then the more devious of them marionettists realize, we can profit off the frustrations of those who we made work hard but didn't make it... to harass those who don't try enough. They become like really eager at getting the power to try make others feel as bad as they feel for being denied the success they so desperately seek.
This is the way the hunt for success spreads like a mental pandemia throughout society and the eternal sits on the top laughing heartily at all the ego-driven madness.
Pretty disgusting in my opinion. :o)
