Please forgive me if this seems like a very stupid question, but, from your post history, it looks like you are (were?) a mega rockstar who was all ready to go back in 2018, and you were advised at that time by the best and the brightest of SDN that you looked good back then. Did you apply then, or in 2019 or 2020, when you again indicated you had a primary (presumably including a work/activities section) ready to submit?
If so, what happened? If not, what happened? Either way, why are you looking for help in 2021 with something that was ready in 2018? FWIW, while help with the PS seems to be a thing, it's not as common with the work/activities section, which really is a lot more straightforward.
There is a thread where
@Catalystik very generously answers specific questions, but I don't know anyone who actually volunteers to review the entire section. It's generally deemed to be unnecessary, and those who really want that apparently pay consultants to do it, along with all the other concierge hand holding services they provide. Good luck!!!
