Is it worth it?

I am tired to the max, I wake up at 4am to go to work in Valencia CA. I come out of work at 4:30pm drive about an hour to CSULA to attend classes at 6pm Monday, Tuesday and Wednesday. Classes usually finish around 9:30pm to 10pm. Drive back home to San Fernando CA, another 35min to hopefully see my son awake to say goodnight. Is it worth it? Yes, because I know that my son will be proud of me when I am done with school.
