I still have considerable difficulty with interpersonal patience, but I feel I've learned something about the sort of personal patience the article is talking about.
Basically when I feel myself becoming inpatient (it's a feeling in my chest, kind of an anxious feeling) I will stop and take a little breath, and give myself a chance to "reframe" mentally a little bit.
I tend to be obsessive about thoroughness as well, and while I still struggle with this, I've learned to "8-bit" things, kind of mentally "zoom out", so to speak.
I've also learned to be okay with not taking the time for something if I don't feel like it (the rule of thumb is to push through minor pain, but to respect serious resistance).
