My writing skills

I want to blog but dont know where to start with. I am also not sure whether I am good at writing. When in school, I was good at english and math and was good at writing too. But now 15 years after school, I am not confident at all. During the years after school I have learnt a lot but knowledge wise I am way back. After graduating in math, I did masters in software engineering and was working at the same time. I studied for the sake of studying and dint really enjoy it. Midway I got married too . Life was too busy with work, studies, managing home(believe me atleast I had to manage somethings at home). Life was really hectic. I dint have time for anything but my husband had lots of interest and energy(his parents genes!!). Amidst all this hectic work, we managed to go for yoga, i learnt some veena too. We had a nice time rushing to yoga classes after work, and while coming back we used to have pani poori . Fun time. Then come back home and think about night dinner. This pani poori has another story behind it. Yes, I am very fussy about food and eating out was a big NO for me. I always wanted a clean environment, clean and tidy servers to serve me. Only then, I used to get the interest to order and to enjoy and eat. But my husband changed my attitude.(partial success??) He used to tell me that to get immunity we should eat on the road side. Thats how I started eating outside and we used to eat pani poori and masal puri every other day we go for yoga classes.
After 2 years of marriage when I was doing my thesis I got pregnant. I still believe the professors passed my thesis because I was pregnant and I dint have time to do it again.(Sometimes I think very low of myself).
