Add. More. And. Hope.
The + sign is lovely. Whether it stands for good job!, or but wait, there’s more!, you can’t really go wrong with it.
It’s hopeful. There’s more to come, something more than what I have now is coming my way. Something worth waiting for. Whether it’s just +20% more of my shampoo or adding an extra guest to the invite, there’s usually something to benefit. There’s a bonus somewhere associated with a + sign.
Hopefully more +s are coming into my life.
