If there was one word that summed up the good poker players of the world, that word is discipline. Good card players have the discipline to wait for good hands and not play bad ones just because they are bored. Good poker players have the discipline to know when to fold a hand. Good card players have enough discipline that they can overcome the emotional hurdles that every poker player gets. Good poker players also have the discipline to constantly work towards improvement.
Every one of the things discussed above is a factor of major importance in becoming a successful poker player. This is true for both online poker and its conventional offline counterpart. Therefore, if you want to become a successful poker player, you are going to need to hone your discipline to the point where it is easily your strongest quality. While this might not seem necessary to some, please understand that it is the single most important thing that you can do along the road to becoming a successful poker professional player.
In addition to maintaining discipline in all of the things you do in online poker, becoming a successful poker player also involves study. You are never going to get better unless you go back and analyze what you have done. This is extremely easy to do in online poker because all of the websites provide you with hand histories that you can comb over to see what you did right, what you did wrong and what was somewhat in between. Studying is one of the most important things that successful poker players do. You will notice that most successful poker professional have excellent memories of past hands and this is primarily because they went back and studied those hands in detail.
Even the most studious card player will not become successful until they start applying what they learn through study. It is one thing to know that Q-10 is a terrible hand in early position, but it is quite another thing entirely to actually have the discipline to fold that hand when you haven't seen anything good in two rounds of the table. Likewise, it is one thing to know that you tend to chase flushes when the pot odds are against you, but it is quite another thing to actually fold that four flush on the flop to one bet instead of stubbornly pushing through. Application of your study in practice is the thing that will ultimately make you the successful card player you want to be.
