My lovely neighbour retired and, as a paying hobby, joined a blogging circle. (No idea whether it did actually pay.) All the bloggers posted "living the dream" blogs.
I would read her blogs and think I wished I lived where she lived. Except that I did live where she lived, right next door.
She posted about her love of gardening (genuine) and include photos of her wonderful garden. Except that she didn't ever post a photo of her whole garden, which often looked as damp and windswept and weedy as mine, just close ups of individual flowers. So she didn't need her whole garden to look good, she just had to have enough individual flowers scattered around to photograph.
I remember once when it was cold, grey and had been pissing rain non stop for three days. She posted "There's nothing better on a chilly day than a bowl of home made soup." And she posted a photo of her soup - red tomato soup, in a green bowl, with a crusty roll on a side plate, a curl of butter, and a nicely folded napkin.
I realised I'd had soup for my lunch too, but I hadn't colour co-ordinated my soup with the bowl, or bothered setting the table.
That was the difference between her "living the dream" and my bleak "when-will-it-stop-raining" mood. She'd colour co-ordinated her soup with her bowl, just to get a nice photo for her blog. I'm sure she didn't normally fanny around with her soup.
That's the secret, I think - spot the good details, like the day your daughter's hair looks good, photograph that, and imply that it's representative of your whole life.
