I'd put my kids to bed at 8, and I'd sleep until 1-2 am, then get up and study til the morning. I'll tell you, I don't know how I did it, but I did. Graduation was on mother's day, it was one of the best moments of my life.
I worked as a night shift janitor at the school 11pm to 7 am. Got free tuition out of it. I never slept. Finished in 4 years. I did summer school to make up the 1 match class i was behind.
It was damn hard going back to school after 7 years, but i had prep school for a foundation and a former job for a septic tank company to motivate me not to fail.
