To turn as a Pro in gambling isn't an easy thing. Many users have mentioned of different qualities required to be a Pro I'm gambling. The basic and very important one is the big sum of money. If you've got money, you can spend and understand how things happening. Not everyone get this opportunity. During the play you can win/lose, but from every experience you need to learn something and focus on creating strategy. This could make a man atleast 60% gambler.
It wouldn't be so easy but I believe it will be worth it. Attitude is the hardest thing we need to change or fix if we want to be professional, a lot of people struggle with that, even those who are in the industry already. You need to be unique as well if you want to stand out. Respect to other people can help you in many ways, even if you are losing show some respect to the opponent even though it is hard.
