Yes exactly, the willingness to wait. But we're not talking about waiting, we're talking about taking it day by day by focusing on what you can do during that day to the best of your abilities.

Hence, patience is irrelevant, if anything a wrongful framing of the situation that doesn't help anybody. Show up as much as you can every day for yourself and you won't need a single drop of "patience".

We are talking about waiting. The time between when you start and when you reach a level of useful proficiency is time you wait through. You don't wait doing nothing, but you certainly do wait. Yes, it's not a useful way to frame the situation, but that's what makes impatience a flaw. If an impatient person could distract themselves from how much longer the task will take and concentrate on actually performing the task they would not be impatient, they would be a normal person coping with the impatience everyone feels.
