Your story is written brilliantly. Before the "tipping point," most of the sentences are short and rapid. My mind was racing to keep up - in a good way.
After the "tipping point", the sentences are more elaborate, with commas replacing the periods, signifying a mood change. Again, I thought that writing style was brilliant.
One suggestion: you may consider breaking the story into two sections (pre- and post "tipping" point) using Medium's page break. I think it could add to the depth to the differences of the two. Just something to consider.
Overall, fantastic read with accurate descriptions. You hit the nail on the head with the corporate hustle-and-bustle. Thank you for sharing!
