Missed opportunities and bad decisions can result from ignoring what other people are doing. If, for instance, you fail to notice which cards your opponents are dirame goldscarding or collecting, you might unintentionally prevent yourself from forming important melds or reveal details about your own hand. Overcommitting to a single strategy and failing to adjust when the game's conditions change is another common mistake. A plan is necessary, but it can be harmful to be overly strict with it.
