To succeed in poker, you need to be patient. This is important in cash games and tournaments. If you find it difficult to accept defeat, it is a sign that you are not a very good player. Even the best poker players know that they can't win at poker all the time. Sometimes the outcome of the game is determined only by luck. The more participants in the tournament, the higher the size of the bankroll, the weaker the field, the less bankroll is needed. Emotions make the tournament target a nasty young internet guy with headphones who thinks he's playing well and deliberately dive under his raises, especially from the blind ("defend the blind"). But common sense says that such a player is more likely to know how to play than not, and playing with him from the blind (that is, out of position) is really bad. All this takes money from you, you pay with your money for emotions. This is the main aspect of tournaments well, if you get to the final table, the main thing is experience.
