It's not about that it's a hard path but more a risky path. Sometimes it requires you to stop doing everything your doing now and diving into the deep. If you fail you lost all you had, and this is the risk many people won't take.
Also not everybody knows how to get rich, if that would be true then we would have alot more rich people around.
Getting rich is not easy, its an combination of hard work, luck and risk factor, if you get support from all these factors then nobody can stop you in becoming rich in future.
