Almost every great artist seems to invent the self-control to do this, whether it's writing 5 pages a day or waking up early to paint, in many cases as a response to the ennui and disintegration of an overabundance of unstructured freedom.

I'm not one of those guys because it's really difficult to reshape your life into that structure.. But all it really requires is willpower.

For me, concentration of that level only comes into play when I'm fascinated by a difficult problem... it can't be applied to mundane small incremental daily progress.

But maybe if I set my sleep and wake alarms differently...
