They are selfish and as long as your parents are supportive go for it. I had to work full time and attend nursing school full time. It was difficult and I wasn't an A student but I survived. I have been working as a nurse since 1991 and currently attending graduate school, working 50+ hours a week and maintaining a family. If it wasn't for the support of my wonderful husband and kids I couldn't do it. I am still not an A student but when I graduated in 2010 with my BSN I received honors which was surprising to me. Keep your head up and good luck!
