Patience is treated as a virtue and is really a set of conditions. Nobody waits well while staring at a moving chart with an empty account target and no defined criteria. Almost anyone waits well with alerts set, a written list of qualifying setups, and something else to do.
It is worth distinguishing from hesitation. Patience is not taking trades that fail your criteria; hesitation is not taking trades that pass them. They feel similar in the moment and have opposite fixes.
Engineer it. Alerts instead of watching, a scheduled review during dead hours, and a record of skipped trades so that waiting produces visible output. See boredom-trading for what happens when it fails.
