There are few useful things to remember when you are creating your first blog:
1. Don't freak out!
You think you are the only person in the world who doesn't have a blog yet. Relax!
There is nothing scary about it!
2. Choose your style.
There are different blogging styles so you should consider which one is the right for you.
3. Think about how often you want to blog.
If you don't have enough time you should choose a style that allows you to blog just 2 or 3 times a week.
4. Keep an eye on the spammers.
There is nothing wrong in deleting spammers' messages.
5. Enjoy yourself!
Choose topics that you are passionate about. There is nothing more important than this!
