Programming is not a fight-or-flight battle for survival. It can be a quite comfortable career. Pushing yourself past your limit on a regular basis isn't going to improve your job security, it's just going to burn you out and ultimately have the opposite effect.

I had a really good Ask HN about 8 months ago on this topic where I got a lot of good advice from people here.
