To write or to not write?

I'm reading many different websites on the art of writing a novel but feel I'm not actually skilled enough to have it be good. I find ideas easy but its the craft of the language on paper that when re read has the feel of a twelve year olds work. I write everyday in some form or another but I'm only as skilled (can I even call myself skilled at all?) as I am and no more. Is there a point in writing a story that's shit and only I will read it? 

I hope so. How important is it for me to have written a story at all? Very. 

It's always something I've felt I wanted to achieve. But surely if it's rubbish, then it's not really worth the time? 

I think I should write it because the 'writing of it' will give me pleasure while I'm doing it. I think I have my answer. 

I mean after all, I've written this blog for three years and it has no point and is shit. I've written a diary since the age of eleven (I'm 39) and that's pointless (although useful for quantifying my time on the planet). 

Fuck it, I'll plod ahead with it.
