It is without a doubt possible. I am working a full time job, have a wife and a 1 year old daughter. I am enrolled in my second semester of an ADN program. You will be tired, you will be cranky, you will contemplate quitting, but then you will remember that your two kids at home are depending on your success, and you will push on. You will have sleepless night full of studying, and completley wasteful days at work falling alseep. Eventually you will run out of hours in the day, and you will start dreaming about school as well, but then you'll wake up, clean the sleep off your face, and push on. Good luck brother, and dont stop pushing on.
