Specialization. Most of the people who work for big companies do it. They're good at this one specific thing the company needs to get done. They work with other people who are good at other things.

On one hand, specialization is necessary and useful. It doesn't make sense to try and train everybody to be good at everything. As they say, jack of all trades and master of none.

I've been programming a bit today and I am enjoying myself and focusing for hours at end, which has lately been next to impossible for me when working on other things (e.g., website design).

It's made me think about why I'm having such a hard to reproducing the focus and satisfaction I feel when I'm programming when I'm doing non-programming stuff.

Fact is, I've noticed I find it much more difficult to get in the zone when I'm not programming. I feel slow and unproductive (compared with development) and that leads to low morale and avoidance/procrastination feedback loops.
