For me it's a mixture of the extraordinariness of the ordinary... and being bloody-minded

.
There have been a few times in my life where I felt like taking myself out of it. But once, a wren landed on my shoulder, and that was enough to keep reminding me that I'm welcome here.
Plus for me, the ultimate revenge on my abusers is to be happier than them and live better than they did - so I'm sticking around to see what happens

. Lovely things happen often enough.
Oh, and my personal motto is
keep on taking the small risks.
