It gets difficult but it can be done. The best way to do it is to have a strong support system, even if it's only one friend, that friend will be invaluable. Focus on the end result, remind yourself that the time you spend away from your kids now will be rewarded with a little piece of paper that will assist you in providing them with a better life.
If they are old enough, talk to them about it, ask them for help sometimes, asking them to be a part of what you are going through can help them understand better and it makes them feel partly responsible. In other words, they will feel the pride you feel at your accomplishments.
I totally agree with Chaotic Chica, you have to have a strong support system and know that everything you do is for your kids. Even if you don't have many to help you out (or even if you have to pay someone once in a while to help you out), it is all about how you handle it. Stay calm and know that where there is a will, there is a way.
Sometimes, it helps to set a schedule for doing school work. For example, my son goes to bed no later than 8:00 and once he is in bed, I tend to focus on doing my school work and even doing extra work so I won't feel stressed out later. Or if you have a child who has nap times, you can try to do a little bit of studying during those times.
Sometimes, I will study while my son is eating his snacks or playing. Or get up extra early before he wakes up to study a little bit. I hope some of these things help out.
Every little bit helps.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
