Why is it difficult to blog consistently?

I have been rather inconsistent in coming up with new blog posts in this blog. But I admire people who are consistent more than those you exhibit flash of brilliance once in a while. I am just trying to analyse why this is happening to me.

Creative Activity - It requires one to be in best of moods, fresh mind, good amount of energy to keep the creative juices flowing. To think about something deeply enough to come out with a sizable rather meaningful post.

Micro-blogging - Advent of Micro blogging services like Twitter allows us to have half baked/shallow thoughts and yet share it within 140 characters. Then why think deep enough to come out with a full fledged blog post. To argue other way, blogs have been on a rise because of twitter as it allows people to share and converse on those blog posts better.

Changing Interests - My interest in cricket has been constant throughout, that is why majority of my blog posts have been on cricket. Though I am fundamentally passionate in business, my interest about various aspects of business have been changing. Varying from Stock Markets, Software, Marketing, Branding to now Manufacturing. Now I am setting up a factory for manufacturing coconut oil, once it is done my interest will change towards Trading (Copra Purchase and Coconut Oil Sales) and HR (hiring and managing people). One does not develop expertise in anything while his interests keep changing. To have original thoughts and write on a subject, one must be an expert in it.

Discipline - This is by far the biggest reason, why writing is so difficult.

Discipline is doing what we decided to do and not what we feel like doing. (Source).

We often feel like blogging about it when we think about something, but when we sit to organize our thoughts and write about it, we face writer's block. Then it takes discipline to write without quiting.

Writing is a work that matters, and it is our tendency to work on easy things that don't matter.

The first rule of doing work that matters. Go to work on a regular basis. - Seth Godin

Stage Fear - Though we write on the computer alone, there eventually is a large audience that will read it later. That causes fear in us as to what the reader will think about us. Will he spot our mistakes, deficiencies? We doubt our authority on the subject. Actually, what happens is the reader rarely gets into the details and he  mostly believes what is written :-)

Now, should I announce that I would like to write consistently i.e. once a fortnight.
