Congratulations! But please keep in mind that gambling (any game) is never skill but only luck (which is probability). If you go into gambling with the mindset of "I can improve something about myself in order to keep winning more often" then at some point you WILL be very disappointed and sad.

So be careful!

Having said that, I wish I doubled my winnings that fast! Must have been an awesome feeling to beat the odds like that. Good for you!
