I'M almost at the end of a 100-day 'happiness challenge' on social media and quite frankly I don't think it has worked.

The brief set out by the website 100 Happy Days is quite simple and sounded ingenious when I first heard about it: spot a moment of happiness every day and post a photo of it online.

"That sounds fantastic," I cried naively. "I'm sure my life is full of amazing moments I just don't notice and this will force me to see them all with fresh eyes! By the end of the challenge I'll be brimming with appreciation, joie de vivre and, of course, happiness by the bucketloads!"

My husband, one of life's pessimists, said sceptically: "Just a thought...what if you can't actually find something to post every day..? What will happen then to your joie de vivre and buckets of joy?"

But I didn't listen, telling him the challenge was all about 'The Little Things in Life' - and that day I began it with gusto.

At first it was easy, with several events including a holiday and my birthday occurring close together, providing me with ample happiness fodder.

On the 'slower' days I simply posted photos of aforementioned Little Things (some much littler than others, I'll admit).

But there are only so many times you can wax lyrical about particularly nice cups of tea before you start to wonder if a good brew really should be the highlight of not just one, but several 24-hour periods.

Then this week I realised just how many of my photos have been about the baby.

This, of course, is because the little monkey makes me happy every single day - but I began to question whether I shouldn't be posting more things to do with me, rather than someone else.

Then I realised that a lot of my pictures are really quite rubbish and that I am not in any way a skilled photographer.

And here we are: I have lots to be thankful for but I also realise I drink too much tea, am slowly losing my identity and could not take a decent photo if my life depended on it.

Now, I must dash - I'm eating a great cheese sandwich that won't photograph itself.
