What could be a better idea for a blog post than - How to write your first blog post.
Come to think of it there could be many ideas :) yet this is what I chose.
You may be at one of these places :

Know exactly what you want to write...
Raring to go.

Have an idea, but don't know how to go about it...
Confused.

Don't have an idea of what to write...
Clueless.

Where ever you are, consider that it is the perfect place to be.
Why do I say that? Because I've been there and I have finally written my first post.

If some one can do it..
you can learn to do it too - Anthony Robbins

And that is the intention of this post- to help YOU write your first blog post.
Some things to think of before you start writing are -

1. What are you passionate about?What are you interested in? What do you like? What can you spend your time discussing for hours at length? In short, What are your passions?
2. Who is you target audience?What do they do? What are some of their concerns? What are they looking for, on the internet? If you were them, what would be of interest to you?
3. What is the message you want to communicateWhat do you want to tell your readers? How can you add value? What are the key things that fulfill their needs?

Once you have these 3 things listed on paper...
you are half way there.
You have your base ready.
You are now ready to start your blog post.
You can use these 4 simple tips to write your blog and make it interesting for your readers.
These are some basic principals that would help you keep your reader engaged and coming back for more.

1. Use a "catchy" headlineIn this noisy chaotic world of the blogs, your blog post will stand out only and only if it has headline that is irresistible.
   It has to be "catchy", "smart", "snazzy", "hot" enough for people to just want to read the blog.
   It must be tempting and at the same time it must communicate the value for the reader without opening the entire blog
2. Make your post "Valuable"Provide value to your reader.
   Give them what they need.
   Solve some problem that you think they might have.
   Give them tips.
   More value you provide, better it is.
   If you think you can provide more - don't hesitate, go for it.
   More the better.
   
3. "How to" is the key wordPeople surf the net to know how they can - Your job is to tell them how they can get what they desire.
   They aren't interested in what you can do, they simply want to know "how".
   
4. List them downComplex information is easily understandable, if you you list it down.
   Point by point, small chunks of information in neat looking lists.
   Your reader understands that better.
   

Now you are ready to write.
Actual writing a post is very simple.
You can use the following easy to follow steps about writing a blog :

Write 3 to 5 points you want to make to your audience.
