i don't what kind of blog i should make?

You live alone..... not life alone

Anyway, what are you good at? Thats usually the best thing to blog about. Choose something your either very good at, or something your very intrested in. An when I mean very, to a point you like looking up infrmatino about it every day. Not many people would be intrested about a blog about your life. I am not saying your life is boring, but then why read about others life unless there is some unique factor in it.

But its probably better to get out time to time, and experience the world. Most of my summers I spent in a different country did alot of traveling saw alot of sites, and learned about different cultures. You know Broadening my horizons.

Well anyway your choice.

In which field are u interested? make a blog in your interested field as i am interested in celebrities profile so i make a celebrities profile blog.

You should write about whatever you like, talk about whatever you like. Even if you have one line, share it, its a thought, furthermore, its your thought and its your blog.
I HIGHLY RECOMMEND that you join Tumblr (http://tumblr.com) Its a blogging service thats absolutely great because 1) It has a directory, (http://tumblr.com/directory) , so you can follow blogs that that talk about your interests.
2) It has a reblog feature, which means, when you like a certain post, you click reblog, and then you tag it and click Reblog Post, so then the post will end up on your blog, with a mention of whom you reblogged it from...its like the Retweet feature from Twitter.
3) Its very simple, and very visual...though there are blogs that wordy, tumblr is more about visual stuff, like photos and art, so if you have any, post it.
If you want to know more about tumblr, leave me a message on one my tumblr blogs (links below) I could help introduce you and tell you more about it if you ever join Tumblr

Hope that helps, remember, keep calm, and move along, it'll all be fine
