I go against the tides of Tapas xD I liked more the first paragraph than the second!
I find that the second is so full of cliches (as you have said it) that it took me away from the story. I found very interesting the first part because it was not cliche, and it tells me how you writte in a little paragraph. The challenge from my point of view, is to tell the second paragraph without cliches. I don't know, maybe something along this lines:
'My name is Clara Whitten, and I died as an unremarkable person. The last thing I could recall before my untimely death were the bright headlights, screeching tires, and perhaps my last breath. I couldn't help but laugh that my last day on Earth was closing up shop and getting hit by a car while crossing a sidewalk. I suppose I had a good run - at least, the proof that I had existed will be written as part of a statistics on the number of deaths caused by motor vehicle accidents.
So, how if I died can I be telling this? Why am I reencarnating every time i die in the same body with no power over its actions? My after life has become a nightmare, and I need it to stop.'
As you see, I took away the 'saintess' because that will be a term inside your work, and people outside don't know what it is and what entails. The success part is out, and I gave it a goal to make the reader want to keep reading (cliffhanger thing?). Of course my writting its not as good as yours, but that is my idea of how maybe should go?
Good luck finding your desire summary!
