I can't say you are not correct, you're absolutely right but a lot of similar post like this about patience are been posted regularly where low rank members try to remind us of discussions being made earlier.
You cannot over emphasis the importance of patience, in trading as most people loss to the market because for lack of patience.
Being patient is very important to succeed in trading and as you said most traders actually take this for granted and they just proceed into trading without carefully analysing and having a strategy in mind to follow and that makes them to rush into trading recklessly.
Being patient helps to improve other qualities of a trader like discipline, risk management and also elimination of greed. To become successful a trader needs to learn to have these qualities.
