When we are playing poker for a long time, we will become a rush person because it is hard to see the reality, especially if at that time, we are only getting lose. I don't think that the longer we play poker will improve our skills because skill in the poker it does not depend on the longer we've played but how hard we can learn more about the poker game. When you are playing poker in the PvP, you will meet more people who have good skills in poker, and you will not win from them if you don't learn more lesson about poker.
There is a simple rule and that says that the more you do something, the more skillful and experience you gain. I think that it is not bad to do so often for it makes you pass through many different situations in which you think about using and formulating different formulas for winning the game. A kind of mental exercise that pays off in the end.
