How do you blog?

I experienced the same when i started my 1st blog about 5-6 years ago. It was linked to one of networking site. So I just wrote about anything that crossed in my mind. Some very personal. It was really an online diary or journal. But few months back, I started to think about being serious blogger, and monetizing it. At 1st, i was concentrate on one of the blog that used local language. After 3 months, it got PR 2, enough for not doing so much. But I knew i had to start somewhere with more global approach. So I make another blog about making money and all other stuff. Before i made that blog, I had so many things to share that I discover online. So many things, just like u did now. But I donno how to begin. Where do I start? It was scattered all over, till i decide to compile it into one. I didnt really start from 1st things that I discovered, I just start from the earliest thing i need to share. From there, it goes on and on. I havent yet running out of an idea. I just running out of time to write it.
