I need 6-4 hours of sleep a day, and adds tremendous time other people don’t have. Back when I was learning to program I was constantly learning to program while working at my secondary employer and reflecting on how to do better when driving from San Antonio to Dallas. Those saved me a lot of time too. If work was slow at the primary employer I was working in side projects which also saved a lot of time. If I needed more time still I would volunteer (or voluntold) for a military deployment to Afghanistan.

I never seemed to have trouble finding extra time, and I did have a family through all of this.
