I think in general women are more driven then men. My wife works full time as a high school teacher, then goes and works on a ESL endorsement at night to better herself even further. On top of all that, she goes to school on the weekends for some sort of gifted reading program endorsement and to learn Spanish.
In contrast, I am like you Steve. I am a lazy bastard. I go to work, come home and that is about it. Sometimes I unload and load the dishwasher, but other than that, I am pretty un-motivated.
Congratulations, does this make her an RN? Is she already talking about getting her masters? My wife is. I think she is going to do that this summer.
