Why don't I blog more often?

I often sit down at the computer with every intention of blogging, but don't.
Why is this?
Been thinking about this lately and have struggled to come to any conclusion.
Is it because I have nothing to say?
Anyone that knows me or has met me will know that this cannot be true as I always have something to say.
Too much on many occasions.
I certainly have the time, in fact I spend far too much time on the computer.
Rephrased that says I waste far too much time on the computer when I should be doing other things.
The only thing I can think of is that I find uploading and editing photos such a pain that I am avoiding blogging because of it.
So from now on I will be blogging more and posting pics less.
Makes the blog a bit boring but it might just get me going more.
