Worked split shifts at two different jobs at the same time. Brutal for a couple of years. 7 to 11, 11 to 3, 3 to 7 and 7 to 11. Young, in debt, too proud to ask for help. A day off of 1 was like a weekend. A day off of both was glorious that one time it happened.

Training yourself to fall asleep quickly at any hour is crucial. If you can't adjust you're screwed.

For even when we were with you, we gave you this rule: "If a man will not work, he shall not eat."

2 Thessalonians 3:10
