writer's block

I seem to have a hard time starting my blogs, or any form of writing for that matter (e.g. cover letters). I have millions of ideas in my head, will well constructive sentences, but once i'm in front of my computer, ready to type, poof, it's gone, like if those thoughts were a work of fiction. I admire people who can write interesting blogs or news posts. They have the knack of either starting their post in an interesting way, keeping their readers hooked or being able to impose the tone of the post within the first few sentences. They also manage to have a very rich vocabulary and seem to be able to express themselves in such colorful ways.


Being a former book work myself, one would think that I'll be able to pick up a few writing skills here and there. I guess I was dead wrong. I would stare blankly at my screen, for dozens of minutes following this algorithm:


1) start typing
2) delete a few words
3) retype
4) sudden flash of inspiration, edit post with more colorful and interesting structure
5) delete entire post because it's crap
6) repeat 1


Then finally, I give up. And then, one day, I get a sudden flash of inspiration, type and save. This occurs once every week or two. I should figure out how i get these flashes of genius and repeat it.
