I have been finishing my degree for 6 years (not including time at Community College). Like I said, you make things work. Do what you have to and you'll have to give up some things, but it's worth it. In the end what does it really matter if it takes 4 years or 10 years to get your degree, if you make the most of the time you have.
I look at my brother and see what he has by not having kids. He has a Corvette, big screen (I have a big screen now) and all kinds of stuff. But with all of that, he is still not a happy person. He still wants more and keeps saying he has to have this or that before he has kids. I was very much this way also before my wife got pregnant. It was like a competition a lot of times. What he doesn't see is that you will never have everything you want, especially if it is all material things.
Anyway, back to the school stuff. Having kids gives you access to tax breaks, financial aid and other opportunities that you didn't have before. You may need to schedule school around work and family life, but if you want it, you can still do it. I go online to University of Maryland (
www.umuc.edu) and can do my work at anytime of the day or night. Look into all the opportunities and be willing to work hard.
