How do I get through tough dev days ?

If by tough day we mean a day where I'm really not feeling it or the like, I don't.
I let it pass by me though music or doing something I enjoy doing, or something random but interesting.

If we mean that the task at hand during that day is tough, then there's no escaping it unless you want to risk losing your job, and I can't afford losing my job. So I ask for help, try to do it one little thing at a time. little progress is better than no progress.
