I wouldn't really consider myself a writer (though one day maybe) but I will say that writing / blogging daily is soooo not easy. When I first started a blog a few years ago, I knew that I wanted it to be an everyday thing. I felt like I had so much to say, and I did and do -- but often am not really sure of where to begin things. I also often have a tendency to ramble on about things completely different from the main point I'm trying to make (for real... happens all the time). And yet despite the difficulties of writing daily, I still do my best to do it. As it is I've already had to take two hiatuses due to schoolwork, but that's life and it happens and I know i'll make it back up somehow.
Writing, in my opinion should be something you love. And naturally, if you force yourself to do it all the time, there is a possibility that you won't be able to spend time on the other things that you want to do. It may even lose the magical appeal that was present that lured you in to that profession in the beginning.
And so while I will continue to attempt to write daily, maybe you all have some comments about how you write. The floor is open!
