Waking up early, having a set routine immediately on waking up (so you don't need to worry about making decisions while half-awake), etc. is one of the best hacks. Particularly if you have to manage other people or otherwise do non-maker work, it's quite likely you'll get more actual work done between waking up and 10am than for the rest of the day.

(5:46am is a particularly good time, especially to the sound of a pager)
