I could see myself building a habit of wandering around unknown parts of the city.
Seriously.
Can't you just sit there at work, drink your tea, enjoy the view outside the window, the birds, concrete, clouds and noise. Listen how people speak, phones ring, listen to this music, composition of life.
Problem? Turn around and walk away. If problem is not solved by then, then try different strategy. Experiment. Failures are essential to success.
More of life will not help you get away from life.
Also, I did not considered one important factor, you enjoy stress and have opinion that it is must be rid off. >:D
My children's births I also remember but the amazement and awe is overlaid with stress and worry - so yes, get outside if you want your heart to relax.
I am not a religious person but I think these are known as "Peak Experiences". [0]
I also experience "ASMR" [1] and maybe these things are related.

Two years ago I spent six months driving across the country, camping and hiking in national parks. I experienced several instances of what I described as "transcendent ecstasy", which sounds like a similar phenomenon.
Believe it or not, there are still lots of areas in the Sierra Nevadas that meet this qualification - ~4hr drive from Silicon Valley.
Takes you deep into Siberia to the winter campsites of trappers. Harsh life but very beautiful.
I kinda have this feeling that I always have to fight for happiness in the city whereas it comes naturally in the wild.
