I have been on the industry for 35 years. I have seen my share of technology evolutions and o have seen the work from a dozen different dimensions. If after all that time, I find the process painful, just trust me -- they can't change me, and I can't change them. You take the warts with the wins and move on. 2-3 bad weeks, 10 good weeks. Life moves on to next quarter. Complete CEO mindset :)
I meant my other productivity drops because I am not a natural presenter so even though I am rehearsing / editing for 2 hours a day, the presentation consumes me / overwhelms me that I can't even focus for the remaining 4 hours or 2 hours. Just do the bare minimum email processing, just survive. Everyone knows it. But by being in that zone of paralysis, I can still deliver a presentation. Sometimes good sometimes ok.
I have this need for the presentation content to reside in my memory cache and other work disrupts the cache quite badly.
But that's not a way to live. The other work stalled for 3 weeks.
