Small victories
A year ago, I bought an SSD hard drive to edit my films anywhere. But it didn't come with a sturdy case. So I bought this card holder (which cost an arm and a leg) at a stationery store.
I couldn't check the size because it was full of plastic sleeves, which I tore out.
When I discovered that not only was it the perfect size, but the cable fit just right inside to stabilize the whole thing... small victory.
It goes everywhere with me now.

(No, that's not dirt inside, it's dried glue residue.)
