I amazed at the ease with which so many bloggers can write and write and write. For me getting even a few words on the page is an incredible challenge. This extends to all other type of writing I need to do as well.
There are times when I just don't know how to say what needs to be said. There are also times when I don't know if what I have to say is worth saying.
I sit looking at the blank computer screen and say... well, just start writing, there will always be time to edit what is there (hopefully).
I can do this... I just have to do it.
