Great outline on peeling the onion.
I know it’s only a working title – but just a reminder that you don’t need to use your metaphor in your title (you can, but you don’t have to).
The associations between getting to know yourself and peeling an onion all work well. The first two are a little similar, and they’re also a little more standard, so you have to be careful your reader doesn’t think I’ve heard this all before. The last four points are a lot more interesting.
This doesn’t mean you need to delete the first two ideas, but perhaps merge them, keep them shorter, or acknowledge that the reader may have heard it before, but tell her you’ll uncover something more fascinating.
Another point to consider is where the similarities stop – e.g. with an onion you can cut straight to the core with a knife, but this doesn’t work with getting to know ourselves.
Well done!
