Great to hear how so many of you are owning this one. I have struggled with impatience for years, despite the fact that I have been working in personal change for years.
My mother always calls it 'the family curse' as
she has the problem and so did my grandfather. Even so, I find I am a lot more over this problem than I used to be. I attribute that to two things. Firstly, I keep practicing awareness for the here-and-now - especially when I am having a frustrating time with things going wrong, or other people not delivering on commitments. I find it helps not to beat myself up if I 'lose it' and just keep going back to the practice.
The other thing that helps me is the growing, inward, recognition that I have far less control over what goes on around me than I used to believe. Reminding myself of that, often, helps me disengage when I notice that impatient fury coming up. And go and find something else to do that lets me break out of the trap.
By the way, in my own work, I argue that impatience is not an emotional problem as such. It is a Bodymind signal (linked to the emotion of frustration) that tells us to stop trying to control the uncontrollable and go and do something more worthwhile in that moment. So it is like a kind of Bodymind 'protest' over the torture we put ourselves through
