I think for me it feels selfish and money hungry sometimes.
When I mention to people that after baby comes I will be going into nursing school and still working and such, people are like "aww, well I know it will be hard being away from baby so much but you are doing it to support your children and in this economy it takes two" and yadda yadda. Well yeah, of course that's one reason for doing it but I also don't want us to be stuck forever. I mean, we live a good life and DH makes decent money but yeah, I'm greedy and selfish and I always want it to be more and better. Baby would be just fine being raised on what we make now but nah, it isn't good enough for me.
Yes, I have confessed to DH that he has somewhat of a money hungry wife and I really feel it's true at times!
