Soul Loss

For all the reasons mentioned above, I believe that these tips are hardly applicable to an ordinary Russian working person.

The inapplicability here is not that it’s impossible, but that it’s dark and slippery right now. But in principle, why not? At worst, replace morning walks with evening ones. Put on headphones and, so as not to waste time, either learn a language or listen to audiobooks.
But this is probably only possible in spring and summer.
