I'm glad I'm not the only one who gets super frustrated when teaching my mom with technical stuff
The way to cure yourself of that:
Picture yourself, elderly and frail. This will happen a lot sooner than you think.
Let's say you can't move as fast as you used to, and your son or daughter is getting impatient for you to move faster and think faster. Pretend you hear your son or daughter getting "super frustrated" in their voice and starting to condescend. Worse, pretend their voice lacks any sense of warmth or understanding, let alone love. Just disgust at how stupid you seem or how incapable you are.
Can't picture yourself ever getting old and frail?
What are types of problems that you weren't smart enough to figure out in school? Let's say that you really want to and need to figure out a physics problem, and you just can not pick it up fast enough for the patience level of the person teaching you.
Then you will realize how selfish the notion of being "super frustrated" is.
It's not about you. You need to step out of your own skin, and into the skin of the person you're trying to communicate with.
At that point, the problem you have to solve is to figure out how to communicate well enough or at a pace slow enough that would enable someone else to enjoy technology vs being frustrated by it.
I hope I am lucky to live long enough to become "elderly". Then, I hope I am lucky enough to have just 1 person who cares about me enough to be patient, loving, and tender with me.
