All these things being said.

If you're like me and people telling you, that you can't do it burns a fire inside you, it's possible if your very dedicated and persistent and have that drive.

It won't be fun but it is possible. You have to decide though if the 80-100 hour weeks are worth it though. Spending 12 hours a day in a casino/cardroom, freezing your ass off. Fighting off boredom and fatigue, all that jazz. If it's really worth it to you nothing we can say will stop you and if it's really worth it to you then you can succeed.
