I played about 10 years and thought that i`m good enough. But one day my friend gave me several books about poker strategies. After these books i began to play much better and it became possible to play on several tables the same time to me.
I think that good players always study(as all other professionals) - from the opponents, looking other tourneys, reading and watching some courses, but i don`t sure that someone ought to pay for it.
You are absolutely right my friend, a good player must always be updated, because now we have seen many players who do not leave their comfort zone and rely only on their previously acquired knowledge, and also fully trust their skills and intuition, and although they do not it is a bad perspective to think like that, we must bear in mind that the greatest teachers are the books, there in the majority of books I really like the experiences that many players have had and have trained them there, those are the books that I really teach, and this is how to trade, the more knowledge you have the better because it translates into making money.
I sure that this is true for everything. Everybody have 2 choices to level-up and both of them are studying. As for poker - you can play with overskilled players, lose money but your skill will increase. Another way - courses, the most part of them free or it is possible to find it for free. The main problem is to find quality courses and i can`t say that the OP trying to sell such courses - he doesn`t tell us anything about it.
