As with every type of diary or journal it's only as good as the information you place in it. For me, I did quite well up until about a month ago. I'd resolved this year to make shorter more frequent entries, which I think I was achieving. Unfortunately, since then I've failed miserably. This is very annoying because the reason I've not made any entries is exactly why I've always wanted to record things. The last month has been chock full of events that I would have liked to record for posterity. I doubt that many friends would find them interesting but I would have liked them here, for me.
Still, chin up, I'll try and start again tomorrow.
