What to do or write about?

Ok so I am so I have not posted for some time because I just did not know what to write about, should I write about school, and just how much fun I am not having? Should I write about how my husband is ready to have another baby, and how I am not quite ready? Not that I do not desperately want another child because I do I just am not sure that I can do everything at once. I work fulltime nights; I am going to school full time, and a mother to a 2 ½ year old. I will be done with my Bachelors in December but have discussed with my hubby about going on for an MBA and MSN which will take another 2 years then 2 more for the repayment of tuition. So that puts me done with school in December 2010 and then able to move in December 2012. That seems like forever but I have learned one thing about going to school it doesn't matter whether I go to school or not the time still passes in four years I will still be four years older (35) and it is my choice if I will have a MSN and MBA or not so I might as well start. My biggest worry is that as years pass it will be harder and harder to conceive. So I am not sure what I so do about having another child? With all of that to consider I have also gained about 50 pounds since Lena, starting out over weight with her I am ever worse this time around. So I think that starting to lose some weight while I am going to school will be the best move on my part. I keep trying to figure out why I have gained so much weight in 2 ½ years, the only thing that I can think of is that I changed jobs from a very active job working in the ER to a slower pace in Labor and Delivery. Since I have tried so many different ways to lose weight and nothing has really worked for me except working my tail off working. So I am still not sure what to write about, so I guess that I will keep thinking about what I want to share with the great big Blogging world.
