Full time Mom, Full time employee, and a Full time student

I look back here I come from. I see my mom, step mom and dad working very hard to make it. Just to survived. I remember looking at them and thinking to myself why do they preach to me about education and how important it is. Not one of them went to college. I know see why education is the key to success.
I, myself am now a mother of two boys. I also work full time and go to school full time. I understand you have to work hard in life, but I want to work hard to achieve and to provide for my family. I don’t want to work 7 days and week 14 hours a day to get by. I want my boys to admire what I do. I want them to say I know I can go to school. I want them to be impressed I raised them, worked full time, and continued my education.
I want my family to have a better life then I did but at the same time be a good role model.
The question is how in the world have I been juggling it all and continue to have the drive to keep going?
