As others have pointed out, it's not too bad in your early 20's. I worked full time, went to school part time, then to another part time job. Mainly because my local didn't offer evening full time schools, and well, I needed money more.

What's odd is that it didn't even feel like much of a chore. You stayed so busy things just kinda flew by.

Thinking about doing that now completely stresses me out.
