The problem is not the Winter, but the city and the dark. I'm in an office which has windows, but all of them look to walls, which are 4 stories high, so absolutely no sun comes in here.
That doesn't seem to help my bad mood. :~/
However I'm looking for a new job, and I hope my next place will be some more light.
I hate artificial light.
The world is full of beauty if the heart is full of love
