The question was what does patience mean in the context of poker. Pick situations that are +Ev, bet, keep betting until the situation changes - but don't recklessly try to take down pots in situations that are -Ev. Recognizing when a hand starts as +Ev and changes to a -Ev situation is a key part of patience.
Extreme example - Hero opens UTG w AsAh and gets called by MP, CO, BTN, and BB - so we're out of position to everyone except BB. Flop is JdTd9c. cbetting here is almost certainly a mistake, but let's say Hero goes ahead and cbets. MP folds, CO calls, BTN minraises, and BB calls. What should Hero do? There's certainly a (very small) chance that AA is good here, nobody's shown any huge aggression, so Hero might be tempted to re-raise/shove to try to take the pot down now.
Patience in this example involves recognizing that pf we were in a hugely +Ev situation with AA, that the flop hits everyone's range way too hard to continue, that trying to take down the pot (actually, in my mind, to put any more money in the pot) is -Ev (shoving will work some amount of the time, but probably not often enough 3way with this board texture), and that we ought to wait for another spot.
As far as playing in position, when to go all in, calling with weak hands, etc. - these are all dependent on situations. There are players I'm perfectly happy to call all in with top pair/top kicker, and there are other players to whom I'm snap folding two pairs. Playing out of position is generally bad - but with the right conditions, I'm perfectly happy to play out of position. Recognizing all the relevant conditions in a situation and playing those spots (what Leo_50 says above) is a key part of playing poker, and being patient.
