You did nothing wrong.
I was getting married and offered to teach my brothers how to make cookies (Lil Sis was going off to college - Mom worked - they'd have to take over some of the chores). Despite eating cookies for a decade or more, he had no time to learn to make them.
So the first time he went into the kitchen and there were NO COOKIES
but plenty of flour, eggs, chocolate chips, and such.....he got out the recipe (on the back of the bag of chocolate chips), looked at it, couldn't figure out why you mixed these ingredients, added those, mixed again, then added more stuff to stir in, and finally (about four steps later) added the chocolate chips to stir in last.
He dumped EVERYTHING in the bowl at once and started stirring so he could get those cookies made faster.
Which did not work very well.
Thirty minutes later, people started coming over (including VorGuy and the former family baker). He was still stirring.....I don't know if he gave up and ate the mess (it didn't look like cookie dough) or tossed it and started another batch - but he listened when we told him how to reduce the four steps on the recipe to three steps (fat, eggs, flavorings, salt, & baking soda - mix well) then add the flour & stir it in, last - add the chocolate chips and any nuts. Baking was kind of optional around that house in the 1970s......maybe a third of the dough got eaten raw, as a "quality check" - wouldn't want to bake bad cookie dough, after all!
He cooks better NOW - but it took a while to convince him that the boring parts of anything were worth the time that they took.
Your UG hasn't learned that lesson yet and I would be willing to bet that he doesn't want to do the boring parts of any job - just the fun ones or stand up in front of the group to get the congratulations on a job well done (no matter who did the good work, he wants the congratulations part).
