I used to work in investment banking in the city of London and later in Canary Wharf. I loved working in the city as it was a beautiful old place, people were very social and having 2-3 hour boozy lunches with someone who you might do business with one day wasn't a rarity (mind you, I moved out before covid, I understand things have changed quite a bit).
Then I switched jobs and ended up in Canary Wharf. For those who don't know it, Canary Wharf is a newly built finance district in the London Docklands. If you've been to Singapore, Dubai, La Defense in Paris or Songdo in Korea, you know the kind of place. Everything is clean, new, modern. Everything has 90 degree angles. Everything has cameras, security guards and cleaning stuff. What it doesn't have is any resemblance of a real city, any organicity or soul.
I hated it. Every morning I saw the streams of suite dressed worker drones pouring from the tube directly into their office towers (Canary Wharf has a huge underground shopping mall/railway station that allows you to go from the subway directly into your office without ever seeing the sun).
I was unhappy. So I did similar things to the OP. I got up earlier and walked there. (I lived in Mile End). It was a nice walk along the canal for a while and then a not so nice walk through smog and traffic, but I didn't mind. I took my lunch outside on the remaining docks. And finally, I got up so early that I arrived an hour before work began.
I spent this hour in a Cafe. Alone. Having breakfast. I loved this hour. I sat there, as the only one not rushing in, getting their "strong capo", beeping their card against the reader and rushing out. I observed the grey and black dressed stream of people. I day dreamed.
It helped - for a while. It was a band aid before I left London all together and moved to Berlin. But most of all, it is a uniquely calm and joyful experience. It decelerates you. The boheme in Paris or Prague has long figured this out. Sit in a cafe. Enjoy a coffee or a glass of wine. Look at people. Daydream. Reflect, be enough - there's a lot to it.
