I get through tough devDays like this:

1. Brew coffee more black than a serial killer's soul in the midst of the Gotthard Base Tunnel without electricity in the midnight during a solar eclipse.

2. Flush the blackness down the throat.

3. Load the Playlist: Mostly Death/Doom Metal

4. Put on over-ear headphones (the ones your coworkers can see from a distance telling them to fuck of with their questions).

5. Code through without pauses (except for releasing piss)

6. If you're paid by the hour: $$$profit$$$

On a good day for me as an SE, the ratio of solving problems to causing problems is close to 1:1
