After reading David Burns's "Feeling Good" and receiving a score on the depression test corresponding to a severe depression I tried the exercises in the book. Though I still struggle with them, they have helped me temendously and lowered the score on the test after only a week. I can not attribute the change only to the exercises seeing as I have been more strict in my meditation regimen (15min at evening). The exercises are very interesting to this community I think and maybe I will write a dedicated discussion post.

With my new found optimism/hope/energy I am much more motivated to start exercising again in the next days, maybe a programming project and again taking up quantifying myself.
